One Problem
I love that it is exactly what I wanted; however, you have to put each attachment on and off many times before it is what I would call somewhat easy to get on and off.  At first I didn't think I would ever get the first one off; and if you have nails you wish to keep, don't do it.  I used a small wrench the first 10 times before I was able to use my fingers to pinch the attachments off and on.
