So far, so good!
Having only owned the treadmill for 2 weeks, I cant say much about the longevity of it but it's been working great for me so far. It is super quiet, which was one of the most important features for me. I typically walk speeds of around 1.3 to 1.7. After I get past 1.7, I can start to hear the motor but it is still very quiet. Also, you can turn off the beeping noises, which is a great feature! It is a bit pricey but it feels very solid and if it lasts a while then it will be a great investment in my long term health. To me, that makes it worth the money. Would be even better if it came with a lifetime warranty.
