This was a great surprise for the money.  I looked at resistance band workouts on YouTube and decided to try it out. At this price why not?  I really feel like I had a good workout after my first try.  The door anchor worked great.  I'm 71 and keeping big equipment around the house is just not possible.  This I just keep in my night stand and any time I've got some extra minutes I do a little workout.  Pleasantly surprised and pleased.  I highly recommend.
