I’m not sure of the model, but I hit a Spirit treadmill in a hotel recently and I didn’t like it. It was slow, felt like the speed wasn’t up to what the display said, and it felt like it was on an incline. Even when I reduced to 0, it looked, and felt, like it was still high.
It was a bit of a struggle to run, and though it might have been some fatigue, it wasn’t a treadmill I liked.
This was a commercial looking model, and I expected more. It’s possible that being in a hotel it was worn down, but it looked fairly new. If I’d have had more time, I would have given up and gone outside.
