Input:
I bought this for my wife's birthday after she "killed" the last two treadmills she had.  She burned out the motors going top speed on the highest incline setting.  Customer support said they really weren't built to withstand that because they didn't think many people could do that anyway...their words, not mine.  Anyway, I mention that only to illustrate that my wife is an exercise freak.  I was skeptical about this machine because of the price but didn't want to spend $1000+ on something if she was just going to crush it.
We've had it for a month now (I've actually been using it too...putting about 18 to 20 miles a week on it)and the wife has been beating on it relentlessly...putting better than 20 couple miles on it every day!  I feel comfortable saying that there can't be many people out there that will use this thing harder than she has and I'm quite impressed with how well it has been holding up.  No loose screws, no squeaks or squeals or noise of any kind.  If it dies tomorrow I think I already got my $ out of it.  By the way, Amazon is the only way to go...every other store I checked wanted $100 more for same thing.
I've lost 8 pounds in the past month using it twice a week for 40 minutes each time...haven't changed my diet at all.  Great product, great price.
