Review (3/5): Like it but can easily break.
I bought one at a store for $5. It lasted for about 2 years. I guess I was lucky. This one would have lasted 1 week. The screw loosened. It would have cracked the product. That's how my first one broke. I decided to take off the black lid covering the screws. It works great now but I have to tighten the screws often while working out. I do like this product.
