Review: Made in China - but it's good ! - My first venture into a no cable/extension means of mowing. Not the cheapest cordless lawn mower by some way - but this is a case of you get what you pay for! Well packaged and delivered on time by desertcart. Out the box this mower is straight forward to assemble, but the grass box is tricky if you don't follow the instructions and get the sequence back to front !! Although this cordless mower is built in China and is 90% plastic it is remarkably robust and well made, quite heavy, but that indicates it's not a flimsy cheapo !! Two batteries (which need charging before use), each giving about 20 minutes of mowing, a reasonable wide cut of 38cm means fewer passes than smaller models which helps with the time spent and area cut on each charge. Wet/damp grass is no problem provided the mower is set at 2 or above, but the one fault this mower does have is the wet clippings don't discharge to the rear of the collecting box and tend to choke the exit port, way before the box is full, resulting in clumps of wet clipping deposits on the lawn. Having said that I wouldn't normally mow when my lawn was wet - I just wanted to test the machine in all conditions. The handle is height adjustable and the start operating process is simple and easy with a slight delay on motor engagement, noise is acceptable and quiter than some mains powered mowers, maneuverability is okay - just takes a bit of practise. Adjustment for height is easy and all four wheels move up/down together with a single lever and should cater for most situations and length of grass. Black and Decker are a well established name in power tools and this lawn mower does not disappoint - it's well made and I would expect it to be reliable going forward - also mindful of the fact that spares are readily available off the shelf. All in all I would recommend this cordless lawn mower and give it the 5 stars it deserves. Mike
Review: A good mower which is more practical than corded and quieter than petrol - I already had the B&D 36v strimmer and wanted extra batteries for that. It made sense to switch to a cordless mower and ditch the corded hover mower I had been using. The assembly instructions were a bit misleading in places and some of the construction is a touch flimsy. Putting the grass box together was the worst part. In all it's reasonably sturdy. I find it cuts well and a single battery lasts just about enough to do everything I want in one go. With both batteries I'd have thought most people could easily finish a medium sized lawn. The mower handles well and I find it reasonably east to carry when necessary. The grass box indicator is also handy for seeing when you need to empty. Height adjustment is good as I have some very uneven areas to cut. Quite happy with the purchase but it was around £30 cheaper when I bought it.

## Features

- Supplied with two powerful 36V lithium batteries for gardens up to 600m with charge indicator
- Easily height adjustable with 6 heights from 30 to 80mm

### ⭐⭐⭐⭐⭐ Excellent product although it does need it's 2 batteries.
*by M***E on 12 March 2015*

Decided it was the end of buying petrol mowers for me (and my wife who could not start one) After much reviews and comparisons bought the Black & Decker brand, mainly because it has 2 batteries. Only recently assembled and used for first time. Assembly very easy and was ready to use in ten minutes. Can be lifted with one hand into or out of shed or garage doorway. Handles fold easily with swift action device, no more unscrewing bolts. Height setting simple handle easy to use, Possibly could be one lower level for those who like a very close cut on a totally flat lawn, but ideal for my uneven one to avoid shaving high points.Good safety "key" to immobilize if doing cleaning etc. Simple press button start. Motor very quiet compared to petrol. Easy to push around large lawn, although it does take a bit of maneuvering around tight corners. First use got around 30 minutes with one battery. I think that will increase as batteries reach full charge potential after a few charges. Even then, changing the battery in the middle of cutting is simple so no delay if large garden. Cleaning underside easy with no risk of petrol/oil spillage with my old machine ! Easy to store as it folds quickly and can be lifted off the floor if needed. So far could not be happier
