Works great if it stayed together
on December 7, 2014
The product worked wonderfully until it came apart. If you look at the four little discs you'll notice that they just go into the platic part, but there is nothing to really keep them in place. I had one simply start sliding out every time I'd use it, and then suddenly wouldn't stay in. The device with only three discs simply does work. The idea is great, but it could use some finetuning.
