    Happy with the product. You can pull out the roller if you want to mow on the newly prepared lawn. The battery lasted long & charged up super quick too. I have yet to see the longevity of this product but with bit of a care with battery I think it will last long.

    My old lawnmower desperately needs a new blade but is still plodding along, although for months I’ve been talking about getting a cordless mower, especially now I’ve taken on my elderly father’s gardening.
    Well, I’ve got no idea why it’s taken me this long to go cordless!
    I cut my 23 x15 ft back garden a few days before getting this one and it’s out with the extension lead, unroll it, plug in to the RGB socket, plug in the mower, do 2 or 3 strips, stop, move the wires, repeat…
    So I order this while on a deal and although delayed, it still arrived within a few days of ordering. I built the mower in my living room and familiarised myself with the instructions, while putting the mower battery on charge.
    It was showing 4 LEDs when pushing the button, but thought I should fully charge it before first use to ensure maximum power.
    Took it out in the garden, started it straight away and went up and down a few strips – checked the collection basket and it was already half full! There is an indicator “flap” to alert you to a full basket, but as I’ve never used this make of lawnmower anymore (aside that it was my “new” toy!) I decided to empty the basket and start from scratch.
    There is a plastic key that you can remove for safety, but as I live alone I just left this in here, once I’d taken it out to look at and test the “deadness” of the mower without, but unless I have visitors I will probably leave this in place. Now, I know my old lawnmower blade was in need of replacement, but whether that was the case, or just because this is more efficient, I can’t say, but I cut my whole rear lawn in less than half hour, including emptying the collection basket another couple of times and the mower height was halfway!
    I checked the battery in situ and it was showing 3 bars, so I have no doubt that it will give good enough charge to do both front and rear gardens a couple of times before needing recharging so I’m really happy with that; one of my fears of cordless mowing.
    Clean up was just a quick brush down and into the shed. No wires to rewind, extension leads to reel back up and job done!
    I’m now looking forward to mowing twice a week rather than twice a month and keeping my lawn tidy

    Very easy to assemble. Its lightweight but seems to be of reasonable quality. I have a medium sized lawn and it just about coped on a battery charge. The quality of the cut was very good. I think it might struggle on long grass though but overall I’m pleased with it. For small to medium gardens I would recommend it.

    Had been looking for a cordless lawnmower for a while when I noticed this mower on offer for 137 so purchased. I was looking at slightly larger mowers and all metal bodies but couldn’t miss the price offered for this. The mower was really easy to put together, is easily manoeuvrable and the finished cut good. I am more than pleased with this mower although if it wasn’t on offer I would probably of gone for the 37cm model. The only thing that doesn’t seem effective is the air flow flap to tell you that the bag is full. I still would suggest checking the level manually.

    Mower worked much better than I expected. I an used to a petrol mower and thought it would not be powerful enough but it is. We have a small garden and it cuts well and collects all the grass in the box.

    This has been a real eye opener. It’s light, manoeuvrable and cuts beautifully. The collection bag holds a load more than my Flymo and is easy to remove and empty. The machine is very quiet and a charge seems to last a long time. It charges in about half an hour. The cutting height is easy to select.
    I am very pleased with it.

    First battery mower I have owned. I have a large area and it lasts well. The cut is a little disappointing (not such a close crop as my petrol mower) but grass looks good after a trim. I was probably cutting it too short before anyway.

    Good machine. Wish I had gone 20mm. However 25mm is best for the grass.

    Cut the grass which was soaking wet and not a problem. Perfect for a smallish garden and also very quiet compared to my electric mower.

    I don’t think the mower was new as there were signs that the box had been previously opened and there were a few scratches and a lot of dust on the handles etc – I don’t think it had been used but I’m pretty Shure it had been built up – possibly a demonstrator or a return.

    The mower itself was easy to build up and feels like its made of reasonable quality material – the battery was partly charged and took about 30 min to fully charge – Roughly 50min from empty.

    I’m more than happy with the quality of the cut – I cut my grass quite frequently once or twice a week so not sure how it would cope on long grass. Roughly 100m2 and I can cut it twice and still have a bit of charge left in the battery. Very light to push and the roller stripes the grass better than I expected.

    I marked it down a star as it failed to start on a few occasions – Not to worried as Yard Force extended the warranty for an extra 2yrs free of charge. I think that excludes the battery though.

    First, review as too early to cut grass (January)
    Seen a good deal on Amazon for the mower, so bought it.
    I’ve always used petrol mowers, but want to avoid yearly maintenance fee’s, and only have a small area to cut too. So far, impressed with the look and build quality, look forward to testing in the coming months which I’ll add a further review then.

    Easy to assemble, cordless makes life so much easier than corded, cuts nicely, so far so good, battery has plenty of life left after cutting front and back garden.

    Cordless wins!

    I previously had a petrol mower which was heavy and difficult to start. This is the complete opposite. Lightweight and easy to manoeuvre, best of all it gave a great cut to my lawn. Robust and a good battery charge too. Very pleased with the mower.

    Excellent cordless lawn mower, light weight, I’ve used it only about 4/5 times and gets really close to edge. And a good size grass bucket.

    The lowest setting isn’t really that low and the roller doesn’t really stripe the lawn, apart from that it’s great.
