LOTS OF SPACE FOR ALL MY STUFF! Now looks like my regular desk! It has so much room that I don't have to get off to go get something. My coffee, water, paperwork, filing, etc. right where I need it all. I can also move it back and out of the way so I can run on the treadmill.Changing the height needs two people but I suppose you can do it yourself. It's just a pain and my dogs are of no help. A friend of mine bought it then I did, Posted it on Facebook and now I wouldn't be surprised if a couple more friends have bought it. Most desk treadmills are restricted to walking and I wanted to run so I bought a used treadmill and this product is the perfect complement.
