Input:
I was looking for a roller to use at home for my rest days from running and lifting.  I read reviews on a few ab rollers and decided on this brand due to the positive feedback frpm other users.  It is easy to set-up.  The wheels are a bit tight but I used a kitchen mallet and they slid right in.  It comes with instructions in case you do not know how to perform the exercises properly. The wheels rollout/in with ease.  Considering the cost, it is made from sturdy materials and is lightweight and fits well into a small gym bag. I do recommend this product for all fitness levels.
