Right out of the box, save for two small things you screw in, and then the holding pad up top to hold your phone, tablet, etc. …this just works. It's amazing, and it's my first treadmill; so, I wanted something that was going to be easy to use right out of the box. Right now, while I'm still getting used to it, it feels a little small, but I think that's just because I'm not used to using a treadmill.
This feels like a quality product for a good price. I haven't tried using the incline yet, but that's because I'm still getting back into exercising. It does feel fairly sturdy, though the hand rails are a little wobbly if you're not pushing forward on them. There is a bit of a learning curve if you're new to treadmills, but I think, overall, for a first-time treadmill purchase, this has everything and more than what I need.
I definitely will buy this again. Added bonus: it's very easy to register for their warranty. I did get an extended one through Amazon, as well (mostly because it's a first-time purchase, and I wasn't sure what to expect).
