Title: Fantastic Design Makes Up for the Mediocre Power
Review: This is a quality product for the price range. I own several 20 volt BLACK+DECKER cordless yard tools and have been really happy with their performance so I bought this mower hoping the batteries were interchangeable. They are not. The batteries that come with this unit (2) are double the size and 40 volts. They take at least four hours to charge out of the box so make sure that is the first thing you do when you receive the package. Set up was ridiculously easy since the unit is shipped 90% assembled already. The shape is impressive and looks like a sleek RC race car except larger (it is the size of a typical mower). The handle to adjust the cutting height is large and easy to use which is good because you will need to start high and slowly work your way down to your desired cutting height (just like the instructions recommend). The unit is very light weight so it was a breeze to maneuver (My kids will be able to take over this chore much sooner)! One battery was able to handle my entire backyard which has a sizeable lawn. There was one area that has been taken over by Tall Fescue which was several inches high. I had to pass over this area at the highest cut-height setting (7) or the engine would quit. I then tried to lower the height to 4 but that was too dramatic a difference and the engine quit. I was able to make another complete pass at 5 before the battery was depleted. I have no doubt that with two batteries I will have no issues mowing my yard in the future. There is a convenient storage compartment on board for the spare battery which is awesome. The power and performance were honestly about a 3-4 range. I still gave it a 5 however because the design and weight or so great and I was able to push this mower with more ease than the self propelled walk behind gasoline mower I used previously.

Title: Batteries make this nearly useless
Review: Needing a new lawn mower at the start of COVID, I didn't want to shop in person, so purchased this. The mower itself is lightweight (not surprising, since it's mostly plastic) and maneuverable. Granted it has been over 2 years since I assembled it, but my recollection is that it was straightforward to put together.Unfortunately, a major problem - and what brings my overall rating of this mower to just 1 star - is that the batteries don't last long enough to do the job. My home sits on a quarter-acre lot with a house, shed, driveway, several trees and a garden. If the grass wasn't overgrown, I could mow the yard in 45 minutes with my old corded mower. The description of this mower stated that just one of the two included batteries would last the amount of time I needed to complete cutting my yard's grass. Unfortunately, this was never the case. The original two batteries combined have never lasted the 45 minutes that were promised for one battery. On top of that, only one charger was included, so only a single "round" of mowing could be done at a time. With a charging time of several hours, I often had to wait until the next day to resume mowing.After a couple months of frustration with the above situation I purchased new batteries and a second charger. When I made the purchase, I stuck with Black & Decker batteries. I verified that the voltage, amps, etc. were the same. The batteries also looked identical in the pictures I could see. Unfortunately, when the batteries arrived they were obviously not right for my mower, as the connectors were wrong.Last year I purchased another replacement battery and charger. This battery was stated to have twice the capacity (amp-hours) as the originals. Unfortunately, it also fails to last anywhere close to the 45 minutes (let alone the 90 minutes one would expect) I need to get the job done. At least I can get in two "rounds" of mowing now.Another frustration is that if the grass is overgrown and thick, the mower stalls quite easily. With the battery situation being what it is, this often happens as I need several days to mow my yard. The method I've adopted when dealing with this is to "pop a wheelie" with the mower: Where there is a small patch like this I will just lower the mower onto the patch. Where there is an extended stretch of such grass I mow over it multiple times in order to get it to the desired height. This can extend the time needed to cut the grass quite a lot.When I was younger it seemed that Black & Decker had a pretty good reputation. Unfortunately, this experience, a few others, and some things I've seen & heard from other sources, leads me to conclude that they no longer deserve that reputation. I certainly won't be buying any more of their battery operated tools in the future.Update: At only three years old the starting mechanism failed. I tried to fix it myself, but found that beyond my skill. With the problems mentioned above, I wasn't willing to put more money into having it repaired and bought a replacement from another manufacturer.

Review: Had it about a month or so. I’m impressed with this mower and battery life. Two batteries let me mow our front yard, the neighbours front and our back....with one bar remaining on the second battery. And really, one could spring for a third battery if your yard is larger. Today I mowed the back which had gotten away from me in places and the motor didn’t even notice the thicker spots.I do keep a higher height setting as I prefer longer blade length. The unit is reasonably maneuverable but I find myself being a bit more cautious because it is mainly plastic decking. Very light though which is nice and helpful when mowing near flower beds, etc.The folding handle is a bit awkward but I don’t really need to use it. If I did, I would get the hang of it I sure.So far, I happy with this mower.

Review: 2 Years on and it's gone to the great recycler in the sky.PROS - I love the lightweight and maneuverability. Does a good job on the edges, leaving little that needs to be trimmed.CONS - Given that my backyard lawn is about 4000sqf, the batteries don't last as long as I would think they should. The first cutting used a full battery and 2 indicator lines on the second. Second cutting, 1 full battery and 1 indicator line. Third cutting managed with just one battery.Charger takes about 4-5 hours to recharge the batteries.If I had grass in the front yard, I would be returning the mower, as it would not have the battery capacity to do the whole yard in one day. But it works for me, so the cons don't outweigh the pros.Update after 10 weeks of use:The cons now outweigh the pros, mower stalls out at the site of long grass. I missed one cutting and had to raise the cutting height 2 settings just to be able to get mower to run without stalling. Then had to cut it again the next day.Want to fix the charger problem, that'll only cost you another $86.82 for the fast charger. Not sure if you can put hot batteries in that chargerThis is the first Black and Decker product I bought in 40 years, I now remember why. They are built for the occasional home handyman.Certainly glad I bought it at half price.

Review: This lawn mower has a lot going for it. Fast and free shipping were a plus. Easy to maneuver. Easier to use than I thought after reading the instructions. It took several tries to get the gears on the handle height to mesh properly, and I wonder how long they and the lock will last as they are just plastic and seemed to strain to work. One charged battery did half my yard (about 30 min). The battery took hours to charge. And, you can not immediately recharge an used battery...too hot so the charger does not work. That was very disappointing. Black and Decker needs to get a better battery and charging system. My SnowJoe snow blower runs on 40v battery and can run through deep snow for an hour and takes a short time to recharge. Had a very hard time opening up the spare battery storage area. Had to use a screw driver to force it open. Again, plastic so not very durable if it does not open easily. Quiet running so can get mowing earlier in the am and not disturb the neighbours. To fold it up for storage, you basically have to take the handle apart.....that's a pain although its not that hard to do. Overall, it met my expectations and I love not having to fuss with oil and gas.
