Bests & Worsts Reviews from Amazon

****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.
