I use ine at PT, but need one for home us and found this one at a descent price. I brought it to PT for them to use it one me and see what they.thought and ut turns out this one is a newse version of what they have. Its fairly easy to use and is comfortable except for the metal plate that ends up on your upper back, but a towel or thin foam would.probably help. When pumping up to stretch the pump works in the opposite direction you would think. When you pump it doesn't fill its on the down that it fills. The other issue is adjusting the head pieces , you have to reach under and squeeze the 2 plastic pices under the device. The old one had a knobs to adjust with. It makes it a little more difficult when using by yourself. I leave it as close to the proper position but still get my head in the device. Overall i highly recommend this. It was strange to get this in an outer Walmart box with the inner box being an Amazon box. I purchased this from Walmart becausue it was cheaper at the time than Amazon.
