I like this money clip. However, I also like my jeans. Unfortunately the back pocket of my jeans seem to have a problem with the clip. Basically, the clip has worn holes in a few of the back pockets and I am left having to purchase new jeans that are well beyond the value of this clip. So, I can't say that I would suggest this money clip to anybody that is looking at putting it in their back pocket, but it works really well to hold the money together (I've had it for a year and it's a bit tough to get money into, but it's definitely not going to just fall out) and can hold 7-8 additional cards in each of the two pockets that aren't right where the money is. This is definitely a plus for AAA cards, insurance cards, etc. that aren't used often but may need to come out in an emergency. I'm currently shopping for a different wallet that may last longer than a year. This one was good while it lasted, but the past three months of using it has cost me nearly $200 in pants (What a nice wallet that would have been, right!?).

Summary:
This is a great money clip if you are going to keep it in a side pocket or in the car, etc. but I would not recommend it for the back pocket people because the clip part will wear holes in your pockets (I've had to replace 3 pairs of blue jeans because of this) after the leather wears off of the tip of the clip.

Pros:
Holds cash very securely
holds more cards than you would guess
looks good (it really does, even if the leather on the clip is a deal breaker - see cons below for better explanation)
easy to access the ID

Cons:
fairly uncomfortable in the back pocket
It gets tough to put in cash if you have a lot
wears holes in jeans - I hadn't actually paid much attention to it due to the fact that I don't spend a lot of time marveling at the brilliance of a wallet, but I just realized that the leather that coats the metal clip has completely worn off on mine. The leather is extremely minimal and is all that separates the metal from your pocket. Basically, like envelope thickness. The metal portion is the same color as the leather (why I never noticed) and is actually fairly sharp. So, definitely avoid this one if you are looking at wallets for the back pocket. I think this is a real shame, seeing as everything else works really well. I'll post pictures to show what I mean.
people can see your cash (it's a con of all money clips)
