Love this lawnmower!
I was slightly worried about some reviewers comments relating to the grass collection box being awkward to fit and sometimes falling off. I’ve not found this to be the case. Yes, it’s a bit fiddly, but once you’ve nailed the technique then it’s fine. It’s fairly lightweight and quiet, and it’s great not having to deal with a cord. Cuts the grass really well and gives nice stripes on the lawn as it has a built-in roller. I have a fairly large lawn, sometimes the battery runs out before I’ve finished, so it’s useful that it came with two batteries- just need to remember to keep them both charged!

Good mower light in use , easily rechargeable.
Good delivery as promised, mower is easy to assemble, light and manouverable to use, good clean cut. Mowed my lawn twice, about 250m sq before I had to recharge battery for nextusage. Value and quality as you expect from Bosch.

Not impressed.
Struggles with wet grass. Batteries are inadequate and quick to overheat. Batteries cannot be recharged while in overheated state. Takes about an hour at the minimum for the batteries to cool down while running for less than that. Meaning a wet lawn of average size could take multiple days to cut. Do not buy if you don’t have a tiny garden. Had mine almost two years. Good idea. Bad implementation. Bad investment!!!

Works well
Good neat cut. Quieter than my last mower. Battery lasts longer too. Leaf collecting mode is a real help - it isn't perfect but much easier than using a rake.

Works incredibly well at what it does, furthermore, very, very quiet
Part of the Bosch 36V Rotak series, it's built to Bosch standards - i.e. very well indeed. Initial setup was straightforward, though the height adjustment took a little figuring out is very easy.I initially used a 2Ah battery in this, but found that this did not provide sufficient power to mow both front and rear grass - I now use a 4Ah battery, which works fine - if you're looking to mow a larger area, I'd suggest getting a second 2Ah battery and using one for each, or invest in a single 4Ah battery.The biggest thing I noticed from using this is HOW QUIET IT IS - UTTERLY BLOWN AWAY on this, in comparison to the corded Flymo I used to use.Thoroughly recommended.

Charger failed for batteries, almost immediately
Great mower however charger for batteries failed after 1 Day, and I am awaiting response from repair center. Not acceptable in terms of service.

The best cordless lawnmower I have owned
A replacement for my old bosch cordless lawnmower and it does the job of cutting my medium size lawns perfectly. Quiet and nice cut of grass, really good to have the option of just machine and no battery charger & battery as already got. Good design with controls for different hand positioning for when you have tight manoeuvrability and slopes. The only small dislikes is when you have to unscrew clips to lower handle as not quick procedure like the next model up which has a sliding handle and doesn't come with a roller which is no biggie. Other than that a great cordless lawnmower buy it.

Not easy to seat battery
OK to assemble, although the irregular shape means you have to be careful not to damage it. Some problems seating the battery, which refused to go in, and then was difficult to extract before having another (more forceful) go. This happened with my own battery and spare. Eventually easier to swap batteries, and the firm seating may be an advantage, as my previous Rotak jerked the battery out of its slot quite often.
