I liked it at first but I'm already on my second one. I have the green one (10-12 lb.). I use it 3-4 times a week for no more than 10-30 minutes each time. I use it with my exercise video that requires one. The first one broke after 8 months of use and the second one is already splitting in places and looks like it will break any day now. I've only used it for 4 months. I will have to try a different brand because it should really last longer than that when used properly, as I do. It hurt when the first one broke. It snapped during use and smacked me on the leg. (Imagine a VERY large rubber band snapping you from fully stretched) So, needless to say...I don't want to experience that again.  As a side note...I never did find a need for the door anchor that comes with it.
