Query: I thought this was going to be so great.

For work and home I have SO many keys and this looked like the answer to my prayers.It was great for the couple of weeks or so, but then it fell apart. It was easy to put back together, but it kept falling apart! And not from a lot of use either. I would just put my hand in my coat pocket only to find that the key ring had fallen apart again! I finally lost one of the pieces so now I've scrapped it. Back to the drawing board I guess.
