Query: Doesn't Work Like I Thought

For anyone thinking a small manual treadmill might be the way to go, you may want to think again. I got this thinking its small size would be an asset, as I could store it anywhere I chose. But I soon found out that manual treadmills are a hell of a lot of work, they are much harder to use than a motor driven treadmill is.As others have stated this thing has no height adjustment on the rear, so in my experience the angle this treadmill sits at means I end up going a lot faster than I would like, and the tension adjustment seems to do next to nothing in terms of changing the speed. I ended up having to build a small wood platform on the back so I could adjust the level of the treadmill as needed.Also after only one use 3 screws holding the bottom part together were already stripped out and I had to re-secure them with wood glue, so its not exactly the best built treadmill you will ever find either.
