I have the wallet filled to max 10 cards plus a tracker, took a little getting used to, but once I put credit cards on one side license on the other(in sales have to pull my drivers license out approximately three times a day) as well as Club cards(sam’s Costco). tracker in the middle is still plenty loud, Wife has a habit of setting her purse on top of my wallet, trackers convenient. Everything‘s working out fine. Way better than the full-size two sided billfold.
