Query: Great Product

The first time I used the Foot And Body roller was at 3:00am after the day I got it. I woke up and my back was KILLING ME!!! So, I put the roller up against the brick work of the fire place, on our FP it has a side that is a full wall. So I stand up with my back against the roller and do shallow knee bends. This rolls up and down your back. Then you adjust it up higher on the back. It loosened it right up after a couple of minutes and I went back to bed, couldn't get back to sleep because I was wide awake at that point, but at least my back stopped hurting. So, I roll before bed and I generally don't need it during the night. I wake up with a lot less discomfort. I also bought the one with the NUBS, but it has not arrived yet.I gave it a four, but really a 4.5 - 5.Works great on arms and legs, neck and feet at least for me. I go to the chiropractor every three weeks. So this is something I can do at home everyday to help out.Great Product for the PRICE!!!
