With a few important cards and some personal responsibility....it works great!
****Some reviews stressed security issues.
I get it, if you lose your phone with items in the CardNinja, yes, you are now vulnerable. I understand people getting upset about that but to me that is more of a responsibility issue. Losing your purse or wallet could have the same outcome but blaming the purse/wallet makers doesn't seem appropriate. I feel the same way about the loosing my phone with the CardNinja attached. I put it on there and it's my responsibility to keep up it. Also, fraud and theft protection on your cards are always a good idea.
****I read reviews about it tearing up the phone backs.
Well, it is designed to stay on securely. If it could be pulled off easily, then what's the point. The adhesive is insanely sticky strong. Once it barely touches the phone, it's already sticking. So make sure you have lined up exactly before you start to lower it for permanent position. We made that mistake and had to replace it. We used a little Goo Gone and elbow grease and the remaining glue rolled up, then we just peel it off. No damage done.
It says it will hold eight cards. If you use that many every single day, it will not last as long as people are expecting it to. That will stretch out the material and cause strain on the adhesive, which will start detaching slowly.
It seems to be mm smaller than the size of c/cards. Which is smart, that feature along with the stretchy material is what makes it fit snug around the cards.
My husband has had his CardNinja for a few months. Well since October, it's February. He keeps three cards in it and that's about it. Sometimes he will place a bill in it right before he walks into the store. The structure has not been compromised at all. Putting money in it and then pulling on the material a few times a day will weaken it faster.
So does it work as directed, not entirely. However, using it like my husband to keep up with, c/card, and a few i.d. cards, along with a little responsibility, it works fine.
The photos are of me placing mine on today.

Easy to apply, good for commuting
All right, so I received this item on July 26th; as someone who commutes in the city on public transportation, it is important for me to have my transit card ready to swipe and honestly, I hate having to dig for it when I'm walking. This thing fits neatly onto the back of my Google Pixel Otterbox case, without blocking the camera, natch. I was hesitant at first because I wasn't sure both my transit card or my work key card would fit well enough but so far they haven't budged! It took a bit of getting used to it when I'm not working but I merely slide the two cards out if they aren't needed and leave the CardNinja empty. I haven't tried it with cash or personal credit cards yet but then again, I'd be anxious to do so. I bought this for the purpose of commuting and so far it is working out great.

Most Useful Thing I've Bought on BTA-MALL. Everyone Wants One. (2nd Time Purchasing)
I used my original Card Ninja for over a year before it started to fall apart, and I put it through the ringer. I always carry at least 5-6 cards and a couple business cards, which is far more than recommended. So the fact that it lasted for over a year made me super happy. When it was time to repurchase, I got it in this beautiful blue color to match my case, and I love it even more. I am ALWAYS getting compliments on my CardNinja. Everyone who sees it wants one, and I understand why.
Ways I have used my CardNinja:
Carrying my license, debit cards, and business cards so I always have them on me - even if I don't take my purse somewhere.
Carrying cash at a garage sale so I can look things up online to make sure I'm getting a good deal AND have my money with me.
Carrying a ton of business cards at conferences and events so I don't have to juggle so much junk.
Of all the things I have purchased on BTA-MALL, I honestly think this was the most useful. I knew it wouldn't last forever when I bought it, but for the price, a year of convenience is WELL WORTH IT!

Works exactly as advertised, except I don't think 8 cards would be wise (they claim it can hold 8 cards). I usually have 3 to 4 cards and a $20 bill and it works great.

Scuffs after a while
Great for the first month or so until it started getting scuffed by other things in my pocket or by my pants themselves. The material is really soft, but this has its pros and cons. The outside gets this unattractive look with little grainy balls attached to it and little scratches and scuffs after long use. Kind of expensive for what it is as well.

Very pleased wit the
Exactly what I wanted. It is much sturdier than the free one I got at an event. Holds my building ID and metro card firmly but the pocket is stretchy so more can be added. Pocket is fairly deep but won't cover items completely. Very pleased wit the purchase

I got my first one at a museum shop years ago. It lasted 2 years before stretching out to the point I needed to replace it. There is an element of operator error at work here: I put 4 cards in mine. Drivers license, credit card & 2 debit cards so it gets a workout. It is important to pay attention to how tight the fit is over time. These aren't immortal & also not expnsive so if you can afford a smartphone, you can afford to replace this immensely handy ID holder from time to time. I am buying my 4th one in 8 years so I am satisfied with its durability.

This is a fantastic addition to your cellular case and a great alternative to a wallet case. I've had this CardNinja for a little over a month and it works fantastically. It holds my license and main card securely. I have not had them fall out (even after turning upside down and shaking vigorously). Stick on the back of the phone really well, too. No lifting or separation.

Insurance) just fine with 5 $20 bills and it is still on ...
I wanted a smaller wallet so I figured why not just get rid of mine and get a phone case wallet. My wallet holds 5 cards (2 debit, 2 IDs, Insurance) just fine with 5 $20 bills and it is still on the slim side, not bulky by any means. So if you're looking to hold some cash and 2-3 cards like normal this case is perfect for you. I purchased mine on sale for $6 so I really can't complain. The cards hold nicely, I gave it the shake test for 30 seconds and it did fine, hardly anything moved.

Great, simple, cell phone wallet
I love having the simplicity of all-in-one, but hated the book-style cell-phone wallet cases. This allows me to attach my cards to my phone with no problem. It fits more cards and bills than I ever had before, with still a slim profile. And the material keeps everything in place, no matter what.
