    Works as advertised
    Have had no problems but does take a little time to connect and initialise when inserted. Have found all the features straightforward to use for thermal imaging and the hardware is very responsive when traversing a large area with no discernible jitter. The battery life seems more than good enough going by the level meter in the app. Have used it around two houses so far and still had 50% left. The lightning connection is very solid and not fragile as i had feared before using it. Connects through the gap in an OtterBox protector using its extension mechanism. Good little carry case works with lightning extended after a little adjustment.

    Great buy.
    We bought this for a more in depth view of a drafty house and it was able to accurately pinpoint areas where cold was coming in for us to reseal or cover. The thermal images are easy to view and the app easy to install on our phone and tablet. Happy with it.

    Helped me find those cold spots in the home, and dropped my daily gas bill down from 14 a day to 4 a day…. so its already saved me more than I paid for the device… happy days

    Battery life could be a little longer… but for the size of it you can’t really complain.

    If you want to view into the world of infrared, this is the tool to use with your iphone. It requires IOS 14 or greater. The app, with iphone, shows, in excellent detail, images of heat traces and distinguishes hot/cold surfaces very well (white through to the blue spectrum). Tracing central heating pipework is useful. Looking for hot/cold spots is vital if there are issues with draughts, cold spot and air blocks in pipework.

    Looking at printed wiring boards for high temperatures in components is another use.

    You can record video/still images to the iphone for viewing later. All images are captured by the FLIR camera -NOT the iphone. The rechargeable battery will last around 60mins. High Recommended.

    Love this. It’s perfect to identify heat sources and locations. Also good to use if you ever have a water leak where you can detect where the hot water has gone in your ceiling and walls.

    Great camera for the price, app is slow and glitchy.
    For the price, it’s great to have the such a camera. Starting up however is boringly slow and I believe the app glitches often. Still very usable though.

    Excellent product with only two small drawbacks. If you have an older phone (mine is a 1st gen iPhone SE) then you won't have full functionality, although what you do have is pretty good. Also, the available desktop app only works on a PC. Unbelievably they have not designed a desktop app for Mac which is very disappointing. Flir made this product for an iPhone yet there is no support for further use beyond the phone itself. Hope they get it together on this one.

    In hindsight I should have bought the next model up. The model I bought does not allow separation of the visible and IR pictures so interpretation is a little difficult. good for personal use.

    Golden Review Award: 10 From Our UsersFLIR Edge Pro is amazing!
    I was worried as a number of the reviews are a bit negative – and it looks like they refer to different (less powerful) models. I’ve just received my FLIR Edge Pro, setup was super simple and the photos it takes are amazing!

    Can easily see some insulation issues that were picked up by a contract with a significantly more expensive camera. Examples attached. It seems to do a nice mix of visual plus infrared (though you can select one or the other).

    Camera setup is really easy, no instructions needed. Download app, turn on camera, allow app to connect to camera, and take pictures! I’ve not yet had to read the manual and everything is really intuitive.

    By default you can select 1,2 or 3 spots as well as highest or lowest spot to show the temperature of. It also has 1GB free cloud integration (FLIR Ignite) and you can re-edit / move the spots on there.

    Golden Review Award: 2 From Our UsersSuperb tool for finding insulation problems in your house.
    It’s expensive I know, but trust me, it will find so many insulation issues in your house to fix that it’ll pay itself back. And the second hand values are quite high, so once you’ve finished you can sell it on.

    Battery life is poor and image quality is low, but you’ll get the idea quickly enough.

    Since I bought it I’ve completely insulated my bathroom, added insulation to various walls in my house, added underfloor insulation where I can, and so on. It’s a really good tool – the house is more comfortable now.

    Worst features are the lack of overlay and the long turn on time. But all-in-all, quite a handy tool. And very worthwhile for the money.
