Good size and quality
This wallet is great. Really good quality and design. The design allow you to have enough card in the quick access slot. Easy to retrieve frequently used cards. The secondary card space protects your additional cards without being bulky. The elastic cash strap holds folded bills nicely, but can be a little cumbersome to retrieve and replace the bills. It is a modern design with the thought that cards are the primary way of paying. If you use cash, you may want to find one with a money clip for easier access. I did not want the protruding clip and love the minimalist size of the wallet. It is slim yet very sturdy. I went from a slim leather design to this, reducing size and weight and have never looked back. I recommend this for anyone that wants a wallet they can carry in their front pocket and still have all the items they need.

Sleek, Functional, and Perfect for Everyday Use
This slim card holder is exactly what I was looking for - compact, the color is sleek and stylish, and very well-made. The pop-up function is smooth and makes accessing cards quick and easy. It comfortably holds my cards without feeling bulky, and the RFID blocking gives extra peace of mind. The metal case feels sturdy and premium, yet it’s lightweight enough to carry everywhere. Perfect for both men and women, and it also makes a great gift. Definitely worth every penny!

Great price vs performance.
Decent wallet. Elastic band enables greater capacity than many mechanical wallets, but plate could potentially catch on pocket. Offered in many colors it seems, I got the black on sale, was much more affordable than a similar one I replaced. Small and compact, many of these have a fold out section, this one does not and makes it much thinner. With a drivers license, a store card and three insurance cards, mine is less than .75 inches thick. The mechanical component broke on my last one after over a year. I would imagine this should perform as well, as long as you don’t try to put too many cards in there. If anything notable happens I will report back.

Awesome wallet!
This card holder wallet looks super sleek. It's very slim so it can easily fit in your pocket or wherever you need it. It has a metallic feel and seems durable and well made. The lever is easy to press which pops all of your cards up in a nice and organized manner. It's just the right width to hold your cards firmly in place, giving protection so even if you have one or two cards in it you don't have to worry about them falling out or losing them. Overall, a great product.

My new best wallet for only $10
I finally found my new best wallet. Its the smallest one on amazon and it actually cost only $10. This was a discounted price. I thought I found my best wallet last week. I really liked it and was using it. This week, In my browsing I saw this wallet and I liked the way it functioned a little better and at $10 dollars, why noy try it out. It was also the smallest wallet out there I have seen at only .55" thick when you count the cash band thickness (.44" without the band). I loaded this wallet with 12 cards, seven in the main card core ranging in thickness from 020" to .035" thick. The total thickness was .205" thick and they fit nicely in the main card container. All seven staggard out very smoothly and it was very easy to pick the one you wanted and pull it out. I fit 2 more cards under the backplate and 3 more under the cash strap including 8 cash bills. The cards under the cash strap were cards I did not worry about RFID (business card plus car registration and insurance ID cards. I still had room for at least 4 more cards. So unless your stuffing this wallet with cash, it can easily hold 15 cards. The fact that both sides of wallet are expandable is really a nice feature that I saw in no other wallet. Now I did make some easy changes that made keeping the cards square and not sliding around after placement. I glued on two square stops at the bottom of each side of the wallet. Now you just slide the cards in until they hit the stops and it puts the card square automatically and remains in place better. The way the wallet was designed kept everything from sliding out, but the cards would twist some. It only took me about 10 minutes to add the stops, something I hope the manufacturer adds in the future. I also removed the emblem on the band. One more thing I added to make the cash easier to put in place and remove was a small square backplate made out of .025" thick poster board that was about 70% the height of the cash. I glued this to the underside of the band to keep it from sliding around. It worked beautifully. The band is a little rough with what feels like rubber on the underside and made sliding the cash in a little difficult, especially if it was just one or two bills. This backplate only took about 5 minutes to make and install. These are things you don't really need to do, but it improved the overall function more to my liking. There was zero extra cost involved, just a little extra time. I now think I have the perfect wallet that is small and thin and only ways about 3 oz. The wallet I bought last week was about 5 oz and is a little bigger than this one. I still liked it and will give it as a gift to someone in the future. It also cost about 38 dollars, which is what many of the other similar ones cost, some were much higher and I don't think the quality or build was any better than this wallet. This wallet is all metal (aluminum) except the band with no leather. It is very sturdy and should last quite a long while. This thickness of this wallet with 12 cards and 8 cash bills was under .75" thick, definitely thinner than any other wallet on amazon holding this much stuff and at 2.5" wide, it has one of the smallest widths. If you can still get it at $10, give it a try. I think the regular undiscounted price was $29.

Thoughtful Design That Makes Daily Use Easier
This slim card holder does exactly what it claims. It holds more than expected without becoming bulky, the mechanism is smooth, and cards stay secure even when moving around all day. The material feels sturdy and well finished, not flimsy or sharp on the edges. It fits comfortably in a pocket and looks professional. This is a functional upgrade from traditional wallets.

Better than a Ridge, and way cheaper
If you want a compact, push-the-button-to-pop-up-the-cards wallet GET THIS. Before this I'd received a Ridge wallet which I promptly sent back. I liked the style, but the functionality wasn't there. Then I found this - a fraction of the price and better. It feels sturdy and is a great thickness (small, but still holds a number of cards) with a place for folded bills on the side.

Great Quality Slim Carry
I’ve been using this card holder for a few weeks now, and I’m really impressed. The metal design feels sturdy but still slim enough to fit comfortably in my pocket. The pop-up feature is smooth — it fans the cards out perfectly so I can grab the one I need quickly. It easily holds my main credit cards, ID, and a few business cards without feeling bulky. The RFID blocking is a nice touch for peace of mind too. I’ve gotten a few compliments on it already since it looks really sleek and modern. Definitely a solid upgrade from my old bulky wallet. Great gift idea too!
