I like the concept. I hate getting my cards out of the wallet. I thought it might loosen a bit. Nope. Still a wrestling match to get cards out. I like the small form factor. I like that my wallet and keys take the same space as just my wallet before. The edges are a bit sharp in the pocket when sitting on them so I've been trying to keep it in my front pocket.
I love the key holder. I'm at 3 keys an no fobs (my phone is my car key). I love the quiet keys and small form factor. It's quiet!
Overall, I'm still undecided.
