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: Nice Mower So Far - My G-Tech Mower Packed up so Invested in this One. After the 1st Use the Motor Cut out After only 5 Minutes of Use On Reading up though this Seems to be A Safety Feature so It Wont Burn the Motor Out if your Cutting Say To Low Ect And After waiting 2 Minutes it Fires Up Again. So Remember to Not Cut it on a Too Low Setting At 1st. The Batteries Give you About 20 Minutes Use so As Its Supplied With 2 Batteries its Plenty to Do My 2 Small Lawns & The Outside Edges of My House Grass That The Council Own but this Does a Better Cut. So Far So Good with this Mower. Easy to Assemble & Stores away Nice n Neat. Feels Like a Good Build On It Also. Be warned before charging the Batteries Back up After USE Let them Coll Down for Like 20 Minutes otherwise you will get a Red Double Flash on the Charger Which after Investigating Means The Battery is Too Warm to Charge, so let it cool. But So Far So Good with this Mower

### ⭐⭐⭐⭐⭐ Freedom!
*by C***W on 9 July 2015*

After accidentally cutting through the power cord of my hedge trimmer once too often I decided to buy cordless, and then when a week later I managed to accidentally run over the power cord of my lawn mower too, as it was over 15 years old and a bit decrepit, rather than try to repair it, I decided to get a replacement and go cordless with that too. Two batteries are supplied. They charge in about an hour each, and they keep the charge well - between the first and second uses was a little over 2 weeks - I recharged immediately after the first use and before the second use I put the batteries in the charger again and the indicator light on the charger went to solid green in less than a couple of minutes indicating that they were still almost fully charged. The batteries have a four bar LED indicator which lights up at the press of a button on top to give an indication of their charge level. (Note that batteries should really be kept in a warm location indoors, definitely not in a shed or garage in winter. They should not be left for long periods without charge so it is best to charge up again straight after discharge, though I leave them to cool down first as a red warning light comes on on the charger if they are too warm - the booklet says charging will start automatically once they have cooled down enough though I have not tried this. The booklet advises keeping them on the charger over the winter when they're not in use - how do you keep two batteries constantly on one charger exactly? - but I'm sure that giving them a regular top up every now and again to keep them charged should be sufficient.) The mower packs enough punch to deal easily with long grass (e.g. the aforementioned 2 weeks of growth at the height of summer) and seems relatively speaking less noisy than my previous corded machine. The batteries have lasted for about 20 minutes of mowing each so far, but rechargeable batteries tend to take a few charges to reach full capacity. There tends to be little warning of the charge running out as you are using it - it doesn't seem to deteriorate in performance at any rate - and it conks out pretty suddenly when the charge has gone. Note that you have to push the battery fully into the slot such that the red plastic sliding piece at the top 'clicks'. You can think you've pushed it fully in when you haven't and when first trying to use it I was scratching my head for ages thinking I perhaps had a dud machine. Operation requires a key to be inserted in a slot on the handle. I'm not sure if this is intended as a safety feature in case you need to clean the underside for example, as there is already a safety feature in that you have to press a big red button along with the squeeze bar on the handle to start the motor, and it will cut out when you release the squeeze handle. (Perhaps it is intended, by keeping it separate, to render the device useless if someone nicks it from your shed or garage? Not that this would necessarily deter anyone.) The cuttings collection box (which is a little fiddly to put together - it would be helpful to have a second pair of hands to assist) has a plastic flap on the top which is lifted by air flowing through it while there is still space inside, and which drops as it fills up, a very useful indicator. Changing the cutting height is extremely easy. The handle easily folds away to make it compact for storage. It's light enough (for me at least) to be able to carry with one hand by the handle on the top which is well place at the centre of gravity. Best of all is the fact that it's cordless. Without having to constantly move a cable out the way, mowing awkwardly one-handed, and having to frequently unplug, roll out the extension lead and plug in again when moving across the lawn and around my apple and pear trees, there is the freedom to move easily and mow in less time. Yes it's an expensive product in comparison to corded models, but it feels worth it.
