I've been using this for about a week, and I've yet to have any issues. I have been hunting for a budget friendly treadmill for a while, and I found this to be the best deal for what I wanted.
So, the deets: I got this on sale for $299. It got to me within two weeks. Setting it up was easy. Moving it....is hilariously awkward, but not impossible. Noise is not terrible, but I wouldn't call it a quiet machine. It's about as loud as a dishwasher or washing machine. This came with oil, but the booklet said that it was already pre-oiled in factory. The belt hasn't moved on me either, and I've both walked and ran on this thing. The cord is short, just to keep in mind for where you want to use it.
Overall: super happy I got this. My legs feel like noodles and I feel awesome getting myself moving again.
