I was concerned that it might not fit my treadmill, but it turns out perfect. Once strapped in place, the desk is sturdy, but it is still easy to remove if needed. The only downside is that you don't have access to the sidebar anymore.
Fits my pro-form carbon TWO, honestly looks like it could for most treadmills there are rubber stoppers that have a lot of width points and straps to secure. I wouldn't lean on it for support but holds a laptop, iPad and everything else you would need to make it a treadmill desk.
Works perfectly on my treadmill - even without using the velcro it is heavy enough to stay put.
I’m able to leave it on my treadmill even when I’m not using my laptop! Great for being in those conference calls you don’t have to participate!
This is an awesome product, but I'm SO BUMMED it doesn't work for the treadmill we got. Our treadmill has buttons on the arms, so there wasn't enough room to place the desk without it being incredibly unsteady. If your treadmill doesn't have buttons through, I would highly recommend this!
