We bought this mower about 5 years ago.... I have been lazy to have the blades sharpened (after this season, it will in fact be the first time!), but I routinely spray WD-40 or silicon spray on the blades to keep them moving. I even left it out on in the snow this last winter on accident, not realizing I had left it out there!! But...it still works like a charm! Tall, thick blades do pose a problem for the mower, but if I'm good about cutting one a week (depending on grass growth), I almost always get a perfect job. And considering it has never had a piece break-off (other than the foam handle-cover coming apart on one corner...no big deal) and obviously no emissions, oil, or gasoline problems, I'd say a great bargain. And I've used it in two homes with rather large yards (1.5 hours max to do the job).
