Complaint on lawnmower?

I got one at Home Depot. It ran twice and died. My son-in-law took it back to them because I had mailed in the warranty which I think was good for two years, and they fixed it and returned it to me. It starts easily now, but do not know how well it is going to hold up again. I would say take it to a lawnmower repair service and let them fix it. These new lawnmowers are a pain. I will buy a used one when I get another one. Sears is not a place where I buy things much, but they do have good paint.
