I have been using professional grade Bosch and Leitz laser measures for more than 20 years, usually costing in the 250 plus range.

My work is indoors and in a lot of large, open, warehouse buildings and range is important to me.

This light, inexpensive and compact unit with bluetooth enabling you to easily draw layouts is excellent for measuring in office and domestic environments, for area and volume functions and the inclinometer is useful. Drawing is reasonably straightforward.

My main criticism is difficulties measuring against cladding. Whilst my Leitz can be difficult when measuring off a galvanised surface, this Bosch is also difficult when measuring off a white metal composite cladding surface.

This affects quite a few of my surveys, so I find myself using both lasers, which wasn’t the idea, and undermines the drawing aspect.

A pity for me as otherwise it’s a great tool, great for use at home, for tradesmen and estate agents, as long as surfaces that the laser is targetted at have a low level of reflectance.

I was divided about getting this or a Leica Disto… on paper this device gives more bang for the buck, so to speak…
And overall it is a very good tool, especially when used with something like the Magicplan App..

I have to recommend a 3rd party app as the Bosch Measure and Go is awful in practically every way…
Another minor niggle, is that when measuring from the base, the device doesn’t sit perfectly flat against the surface, it tilts slightly towards the front which can be an annoyance and quite a bizarre issue to have considering. It also doesn’t have the ‘corner flap’ as found with some other devices…

This is hands down the best addition to my measuring tools set and it has made my life much easier, it takes a bit of getting used to and is in no way intended to replace the measuring tape altogether but can make otherwise awkward measurements infinitely easier and quicker to make.

The memory function is useful for quality control to ensure things are lined up properly and the level feature is very good for precision work.

I’ve unfortunately been forced to use it in the rain a number of times which I had hoped to avoid and it is still working fine so it is definitely at least partially rain proof but I wouldn’t depend on that.

Overall I couldn’t be anymore happy with this product, I suppose the price is the only issue, close to a 100 GBP is quite expensive but well worth it if you’re going to use it daily.

As a keen DIY’er I wanted to purchase a device for projects such as fascia, guttering and new doors. It’s been invaluable and so much more convenient than using a tape measure. Accuracy is great and the ability to take photos and overlay measurements is convenient and helpful. If mine ever broke, I’d buy another in a heartbeat!

Excellent and really versatile measuring tool. The bluetooth linked free floorplan software is very difficult to use on a smartphone screen, and not available for windows pc, so get yourself a 10″ tablet minimum if you plan on doing floorplans with it as well. The software itself is also very good.

Measure is not bad I have been unable to transfer data using blue tooth on all devices I own the app is useless the videos and adverts are misleading on its uses and capabilities

Very accurate and easy to use should’ve grabbed one years ago

I bought this to use with the Bosch Measuring Master app.

The GLM 50 C works perfectly. However, the Measuring Master app was so poor that I initiated a return of the GLM 50 C. The combination simply did not achieve what I needed.
Then, before I sent it off, I discovered a 3rd party app (also free) that works brilliantly with the GLM 50 C – result: I cancelled my return and am very happy that I kept the GLM 50 C.

It now achieves all that I need.

Very accurate and easy to use consistent results, if using outside laser point isn’t very bright if it’s a sunny day but that’s normal can’t expect a miracle.

Brilliant tool that I use every time I need to do diy. Should have bought it earlier.

Item is small but nice in the hand, plenty of information in the multi language booklet plus online, case good as is the rubber edges on the GLM 50C but in this pack there are NO laser target cards as some packages do have them not a deal breaker just print your own, overall a great little thing to have in your toolbox & at this price it’s worth having, I’m not sure I’ll have one if I had to pay full retail though.

Excellent laser measurement floor plan it’s got everything you need I would recommend this laser measure.

I bought this for use indoors. It is very easy to use straight out of the box, saves me time on every measurement, is dead on accurate with every measurement and the laser is very clear. It feels well built and despite being indoors I am on a site where the indoors isn’t completely waterproof and there is a lot of dust. This hasn’t affected it at all. It takes around a second to turn on and is easy to use intuitively (I am embarrassingly poor with technology). Great unit at a good price

Worth spending a bit more for this version. Used to take floor plan and other measurements during house refurbishment. Saved a lot of time and effort. Don’t think I shall ever stop using a tape for total trust of measurements but I gave 5 stars as accuracy well in excess for the first job I used it for.

We have been struggling with some of the more difficult measuring jobs for a while. This has made it all much easier. We haven’t had any problems with the measurement and the memory on the display of previously measured values in the same measuring session helps us to transfer them to our sketches for calculating what we want to do next.

Easy to use and storage and level features are useful

Excellent product. Easy to use and precise, saves a lot of time

great product, easy to use and connect to phone. stores last measurements too which is handy. the companion app is a little clunky but once you get your head round it its fine. the actual measurer i can’t fault though.

I have been very impressed with this laser measure. Compared with the 10+ years old Stanley TLM 130 it replaced, it is compact, lightweight and quicker to take readings. I particularly appreciate the better battery life and the inclusion of a tripod mount on the back.

I regularly use laser measures to check construction drawings against new and existing building interiors and also to take site measurements/quantities for estimate preparation where drawings are not available.

The red laser is clearly visible indoors, but I would not recommend this particular model for predominantly outdoor work. I would have liked the GLM50C to have a wrist strap to reduce accidental drops. Mine remains unscathed after a couple of unintended drops onto hard concrete but I don’t think it is claimed to be “rugged”.

The GLM50C comes with an elasticated cloth belt case which is quite adequate. Initially, the device felt a bit slow to power up (actually just over 1 sec), but this may be no bad thing. I’ve not noticed any problems with accidental power-ons that constantly drained the TLM130’s battery.

The GLM50C takes two standard AAA batteries that are simple to replace however I’ve found that rechargeable batteries work very well.

The rotatable colour display is very clear and the functions are intuitive and very easy to use but the standout feature is the bluetooth connectivity which enables measurements to be recorded remotely via a smartphone/tablet app.

That said, the App (I’ve only tried the Android version 1.6.0) is incredibly frustrating. I know the bar for this type of App is pretty low, but considering this device has “Professional” and “Bosch” on the front, I hoped for better.

The quick sketch floor plan builder is almost impossible to use on a small screen and even simple edit attempts result in insane (*) layouts being created. The app is (sometimes) easier to use with a tablet, but in practice I’ve found this a bit cumbersome out on site.

There are bugs in the wall measurement functions (used to enter wall elevations), with the app insisting that an entered dimension must be wrong (eg a door opening, which the app considered wider than the wall).

The ability to put dimensions directly onto a photo should be very useful, but this implementation is poor. Dimensions are difficult to position accurately and quite often one end of the dimension will stubbornly remain off screen. The magnified view of the target point “under your finger” would be great if it didn’t stray out of sight so often.

Frankly, the only useful part of the App for me is the simple measurement entry/storage/export. Single measurements can be initiated by either the GLM50C or from the App and ultimately exported as xls or pdf. Each measurement entry (grouped into a Project) is date/time stamped and can be renamed, although there’s no facility to record GPS location nor select from (for example) predefined room names and measurement types which would have been so easy to implement.

The GLM50C can store up to 30 previous measurements internally and this is plenty in my experience. This limitation does not apply to measurements stored with the App. The internal measurements are retained after a power-off and will even survive a battery swap.

Tip: If you do decide to get a GLM50C, get yourself a cheap selfie-stick with a 1/4 inch standard screw mount to attach the GLM50C. Having greater reach and not having to press the button on the device makes all the difference. With practise taking measurements (via the smartphone app) will be simpler and quicker – even if it won’t actually replace handwritten survey notes.

Back to the GLM50C itself, there was really only one negative that I think will impact on the measurements I regularly need to take: I do wish it had a flip-out end-piece (like the Leica Distos) to allow taking diagonal dimensions into corners (especially since the GLM50C has a max/min function that’s ideal for measuring into room corners!)

The built-in functions are quite comprehensive (some seem more suited for “outdoor” measurement, so may not be used much), although I do wish that a 3D point-to-point measurement facility was provided somewhere in the range.

Overall, although the current App is a bit rubbish, the GLM50C is thoroughly recommended as an “indoor” measurement device.

(* I wanted to say Escher worthy, but that’s a bad example – the App can’t do stairs of any sort.)

Very please with this purchase. Accurate and compact. A joy to use.

Great bit of kit, just a shame about the phone app: at least for now. Easy to use, seems accurate. Makes surveying jobs a doddle

Never knew I needed one so much until I had one! Great tool to have and incredibly accurate

Use it regularly and so much handier than tape measures

I’ve been using this for measuring rooms and setting out internal walls. This is one of those gadgets that once you use it once, you wonder how you ever got-by without it.

Excellent. Does what it says and easy to use. Compact and professional as you would expect.

Really accurate fits easily in the pocket, does the job

Does exactly as it says and without any problems, read the instructions fully.

Currently fitting new wooden floors plus skirting boards, trim around windows and curtain rails (and doing the wife’s job of shortening the curtains) and fed up with trying to stop my tape measure bending in the middle, coming unhooked, etc. If you have ever had to measure more than half a metre you will know what I mean !!

Saw this little gadget on a deal and saw the accuracy of 1 mm and thought that’s good enough for everything I want. In fact a lot better than I get trying to hold the tape straight. How right I was.

My first thought after delivery was “It’s a bit heavy”. Turned out that was the manual. After the panic over a manual about 40mm thick. I then discovered it was in about 25 languages and the English was a few, not really needed, pages as its all a bit obvious. Just turn it on, point the laser and read the distance. Quick, easy and really accurate. A bonus is not having to write down or try to remember the measurement when I go into the garden to cut boards. Just read it off the display.

OK, Once software gets involved all sorts of clever options are available such as area, volume, indirect (clever) measurements which are possible to work out without the manual but if all else fails and you are male, go somewhere private and look at the manual. I am just happy that I can take straight line measurements without needing my wife to hold the end of the tape. Oh and of course there is an “app’. I have downloaded it but not used it yet.

The bottom line is that it’s useful, accurate, easy to use and easy to keep in tool box. I probably would not have paid full price but now I have used it the full price is worth the expenditure. It does not replace my tape measure but its a really useful addition.

I find the reviews of others help my buying decisions. If this has helped you please click the like so I know I am not wasting my time. Thanks

I’ve used some chinsey ones before and regretted it when I found things didn’t fit as expected. This bosch unit is very accurate even over longer distances. The feature where it can measure between two points on a wall just by pointing it at them is genuinely awesome.
