In general I am very pleased with this mower. Our back lawn is about 200 sqm and the front about 50 sqm. If the mower is fully charged it covers this area easily. The mower is very light and manoeuvrable and the lack of petrol or cord makes it easy to use. I do have two criticisms of this mower: - The first is that the battery does not seem to hold it’s charge and so it needs to be charged before each use. The second is that if you do not adjust the blades correctly and try to cut the grass too long the fuse blows. I was unable to find anyone locally that sold replacement fuses (although they sold the mower) but Black and Decker sent me two replacements free of charge. Once you get used to it this mower is very good and it’s advantages far outweigh the problems.
The mower that I purchased was equipped with a 1200W motor. The battery is 12Ah, which is supposed to be enough for 350m2 of lawn (the equivalent of a tennis court). I find that the battery is insufficient to cut the grass and certainly does not last anywhere near as long as my aspirations. I am not a great gardener, but I try to keep the lawn tidy. The grass length is about 2-3 inches and the motor slows noticeably at this length. I am able to cut about 6 passes of 10metres before the battery gives up completely. A further selling point is the 4x4 wheels. The rear whells can be locked or released giving complete freedom of movement. This doesn't seem to work. I can only liken the operation of having the rear wheels locked to an out of control supermarket trolley. If you are considering this model, think again. If possible get the store to allow you to trial it on your lawn for a while. I regret paying the £144 from B&Q.
