Rated 1 out of 5 by from Total waste of money. I bought this one to replace the previous model which needed a new motor ( £300 plus) after just 4 years. However it was a good mower. The new one looks very fancy but is not a patch on the old model. The main problem is the cutting heights. It claims 7 heights but on my normal lawn I can only use the last two higher settings because anything lower just scalps the lawn. I am seriously thinking of returning this item as “ NOT FIT FOR PURPOSE”

Rated 5 out of 5 by from Just what is needed for a big lawn Moved to a house with a fairly large lawn and didn’t want to continue with an electric cabled hover type mower. Had this for a few weeks and it really is a delight to use and the lawn looks much better for a neatly trimmed finish. The ability to change the height of the cut so easily is an added bonus.

Rated 5 out of 5 by from One charge does our lawn with some to spare In our 70’s so finding patrol mower more difficult to handle.Friends were pleased with their similar Bosch mowers. We have larger lawn so went for a model which would cope with it.Excellent battery life.

Rated 5 out of 5 by from Great lawnmower for larger lawns I've recently moved to a house with a larger garden, and was keen to avoid having to unplug, and re-plug in a lawnmower as I went about mowing the lawn. This lawnmower has more than enough battery for me to give the lawn two passes, and is incredibly easy to use! The integrated rollers leave a nice stripe behind you, however its less visible at the lower cutting height. Once thing to note is that the clippings box will need emptying more often than you think, but a small price to pay for all the benefits.

Rated 5 out of 5 by from Easy to use, lightweight and manoeuvrable I bought this to replace a slightly larger petrol engine mower and so far, although pricey, it has proven a delight to use with good coverage before a recharge is needed. It is lightweight and very easy to manoeuvre and to adjust the cutting height. The grass collection bag is a reasonable size and seems to fill up well. It was delivered quickly without any problems.

Rated 5 out of 5 by from Excellent product I have mown the lawn twice since buying this product and have been amazed that the battery lasted the whole mow. Easy to operate and quiet.
