I didn't think I would like this wallet but I'm sold on it.  It holds about 8-9 cards with no issues and when I release the silicone band on one side it holds enough cash that I carry.

It's a very simple design that happens to work and the price is just right.  You can also get addition silicone bands for $5 off the web site but the band has held up well in the short time I've had.
