I've used these regularly for about 3 weeks, now with the 3 heaviest bands clipped together to the handles. The clip attachments are the sturdiest I've seen--and I've gone through many bands from other manufacturers. These are a great alternative to your dumbbell routine when you travel or if you just want to mix it up. Easy to use and figure out right out of the box! Don't lose the sheet of paper that tells you the resistance for each color band. You can figure it out, of course, but better to hold onto it if you need to move quickly.  The resistance is actually accurate-not the case with other bands. Door anchor is awesomely simple in design, and though the material used in the thick end of the door anchor broke into pieces after a week, it is still thick enough to function- and function well.
