Bests & Worsts Reviews from Amazon

Very efficient and powerful when it needs to be. Draws 2.5 amps with no grass, and up to ~25 amps peak. Only slightly slowed down in the thickest foot tall grass. This makes a big difference as I run a business with this mower. My only complaint is that the blade is 20". It's not a 21" mower. The deck is overbuilt, which for most is a good thing. It could be lighter weight, but not a big deal. But yeah, this mower has changed my life. Update: As for the batteries - the 2ah loses a lot of power in thick grass in the last half of it's charge. That's because it's pulling 10x the c rate, which is a lot of stress on the battery cells. GET THE 4AH battery for mowing. It should perform a lot better in demanding mowing conditions. I cut 6 to 8 lawns using only 6ah of battery. One complaint I have is the tire treads are not durable. They are falling off the wheels after about 600 lawns this season. Little stones and metal edging cut them up. Discharge chute needed to be cut wider for damp/heavy mowing. Blade could have more 'lift' but that's the price you pay for efficiency.
