The CardNinja makes my life that much easier. The CardNinja is adhered to the back of my Nexus 4 case. Yes I have heard that it covers the speaker, so it may not appeal to some people. But I rarely use the rear speaker anyways, so it does not affect me.

The CardNinja is great in ways where I can keep the cards I use most on the back of my phone, and the other 4 I use, in my wallet. I hardly ever take out my wallet as long as I'm using the CardNinja.

Thanks CardNinja!

Two thumbs up

I have had my card ninja for about a year now. I absolutely love it. But, for $19.95, I thought it should last forever. I keep 3 cards in it. I take them in and out daily. The material has stretched a bit at the corners and now, the cards easily fall out. I love it and it's a great idea, but at $19.95 for a little piece of stretchy material, it should last forever!!

Love my card ninja. I use it constantly and it's holding up great. I even changed phone cases and it's sticking on well on the second one. I don't stuff it but the elastic holds my credit cards securely. The only time things fall out is when I drop my phone hard, but that's to be expected. People always ask me where they can get one. 5 stars.

Easy to use, works perfectly. I take it to lunch with my building pass, credit card and 10 or 20 dollars. Perfect for me.

This is perfect for going to the gym. Carries my gym card, license and credit card. Sometimes I stick my earbuds in as well. I've stopped carrying a gym bag. Love it.

I've used this product for about 10 months now and LOVE IT! I rarely carry a purse any more and find it easy to just pick up my phone and go. I take pictures on my phone of non-important cards such as a museum card or store membership card and keep a credit card and driver's license in the ninja. Great product!

I've used my card ninja for 15 months now and it is still going strong. I'm buying a second one to use with my new iphone. This is the most useful $20 I've spent in a long time - I use it innumerable times a day and it works exactly as described. I'm still amazed how well it holds the cards... they simply don't fall out accidentally.

Excellent design and build quality. Since the iPhone doesn't support "osaifu keitai" (an local IC/NFC standard), I bought this to fit my PASMO commuter pass / money card.

Strangely, the readers at the train stations and convenience stores couldn't pick up the IC chip if it was alone in the CardNinja, so I decided to stick my plastic gym membership card behind it and voila, now reads perfectly. Don't know why this is, but all I care about is that it works.

To the CardNinja team-- you guys should definitely look into marketing your product more out here. There aren't many solutions out here to this problem-- and the ones that exist leave much to be desired. I've seen a couple J-blogs feature your product, but I haven't seen it on sale anywhere, even at speciality stores. I think it'd be a hit, especially if you offered it in more colors!!!
