RMA 510 is rated 4.8 out of 5 by 5.
Rated 5 out of 5 by from Even Better Than Expected! Best thing about this mower is it cuts beautifully. We have a good size yard so a bad cut shows big time. Battery lasted long but I don't remember how long, just kept going on & on. I'm tickled.

Rated 4 out of 5 by from Finally a Stihl Lamnmower that looks like a lawnmower The power is a little less than gas engine (as expected), but not significantly less.The battery life is decent. I cut about 5000 sq ft in 30 min and it makes it on one charge.They really should have added self-propelling, but if you have a relatively flat lot that shouldn't bother you too much.I like the classic look, the earlier models were a little too George Jetson for me.

Rated 5 out of 5 by from Excellent Mower After selling my gas mower in the fall, and researching cordless mowers all winter, I finally narrowed my decision down to two options - The Stihl RMA-510 vs a unit sold at big box stores. The Stihl mower is brand new for this year, and had next to no reviews available, so I knew I was taking a chance; the other mower has been around a long time and has plenty of positive feedback. The main deciding factor came down to two things: 1 - The Stihl brand and associated quality with that brand, and 2 - Parts and service availability of Stihl products.Unpacking the mower was a breeze - fold up the handles and it is good to go. Nothing to it. After fully charging the battery I decided to do a test run on my 3000 square foot yard (it is spring here, and the grass has not yet started growing, so I dropped the deck to the lowest height and sheared off the old growth). I was pleasantly surprised with the power this mower was packing. ECO mode worked as described, but I preferred turning it off and letting it run at full power. Bagging seems to be very good with good suction. I did notice some clippings blowing through between the bag and rear flap. I will keep an eye on this once I am cutting growing grass it I suspect it will not be an issue.Battery life seems to be at least as good as advertised. After about 3000 square feet, I had over 50% charge remaining on my AP 300 pack, so that was a pleasant surprise. I am also guessing that I made the mower work a little harder than it will under normal conditions, so that is promising.

Rated 5 out of 5 by from Best mower we've ever used! We reseearched electric mowers for 2 years and we are thrilled that we waited for STIHL and the RMA 510 mower. We mowed our front and back yards (1300 + sq ft) in less than 1/2 hour and still had 1/2 of the battery remaining. Further, the grass was not completely dry and yet all of the grass trimming were picked up by this mower. I was so impressed with the power, efficiency, sound and performance. I recommend this to anyone that wants the best mower money can by. Thank you STIHL!!!

Rated 5 out of 5 by from Great addition to my battery line of Stihl tools Great mower. Was in at charm engine, in Millersburg, oh and seen this mower. Bought it as soon as I layed eyes on it. I have a tsa 230 9" battery cut off saw and love the power it has. So with two batteries I knew it would have plenty of power. Took it home and mowed the grass and yard is 60'x100' and it mowed the whole yard on a 1/4 % of one battery on eco mode. Great product can't wait to buy more battery powered tools from Stihl. Love the handle grip design also. Makes it easy to hold on too when mowing. And less fatigue.
