So I don't usually write negative reviews, but I have to for this one. I bought these to replace a Tower cable system which I used for 5 years and finally snapped. These don't even come close to it. The bands and clips feel flimsy. The door anchor is fine, but it feels like if you pull too hard it'll pull the whole door off the hinges. My two issues are the fact that really cannot do any exercise below the waist since there is no way to anchor at the bottom of the door, unless your door is hung poorly and is flush to the floor. The bands are also way too long. I'd recommend try another product, this one just doesn't cut the mustard.
