After a recommendation from my chiropractor, I've used this clip for at least six months and I'm very happy. The lack of space forces you to stick to the essentials. For me, that includes: Credit card, debit card, driver's license, and work ID. Since I rarely carry cash these days, I use the "clip" to pin down any extra cards I might need to carry on a particular occasion. It doesn't leave a "footprint" when carried in my front pocket and it looks great.
