I am totally Impressed & I don't actually impress easily. The one issue was wheel lock-up when you disengage the self propelled function. A quick read of the manual explains this is normal. All you have to do is disengage a touch sooner & push it the last second & your all set. Should have read the manual first, kinda like they suggest. Duh! As for the free battery. I bought my mower on-line & the second batter didn't come with the mower as I expected. A quick call to HD & it is on it's way. I expect to have it Monday. I am a little disappointed that the free battery is only 2 Ah when the mower comes with a 7.5 Ah battery. I'm guessing it wont get much use in the mower, but i will have a spare for the leaf-blower I bought last year. PS: I love it too.
