I read the reviews before I bought, including those that warned of weak construction. I have experienced no such problems; in fact, I've never had a wallet that feels as sturdy. And the benefits are as advertised: it's half as thick as my prior traditional billfold, nearly an inch less tall and nearly half an inch less wide. Very, very compact and less of an object to get in the way when you sit down. Folding the bills took a little getting used to, as well as sliding the right credit card in and out, but I'll take the trade-off. Having such a small wallet is worth taking an extra second to get a card or move cash.
