Repeat Purchase

That's the highest praise I know. I bought a cycle that I am so impressed by that I returned and bought this treadmill. It's every bit as good as I expected and I've already been recommending these items to everyone I talk with. The treadmill is smooth and quiet, sturdy and built to last under hard use. I'll be back.

Commercial grade quality treadmill

I'm 5'6 and find that the running deck is wide to run on comfortably. Feels like a commercial grade quality treadmill and I expect it will last for a long time.

Great workout.

It works as intended. It took a while to get the belt adjusted just right. The rollers were parallel but not perpendicular to the frame. I actually removed the front covers and found you can adjust the top roller on right side. Now it’s perfect.

Impressed and happy

I was looking for something different and came upon this treadmill. So happy I gave it a shot. It definitely provides a challenge as it's a manual treadmill but I'm impressed with the results I'm seeing. Overall I would recommend this treadmill to anyone looking for a new challenge and serious about fitness!

Excellent treadmill

Great treadmill. Love that it's not electric and you're required to put in the work. The motor is quiet and it feels stable. There's a lot you can do on this treadmill other than jogging/running.
