I use mine all the time. I love it. I bought a Reebok brand and it has been fine for the past several years. It had one problem after i had it about a year and they sent me the parts and somone came out and fixed it. It was about $100 repair. I paid about $600 for the machine and it has been worth every penny. It is so nice when i get sick of my exercise videos. I have it in my garage and i just bring my laptop out and watch a movie while i exercise, makes the time fly by.
I may not be able to lose 100 pounds, but I can lose 10 pounds 10 times!
