Had a bit of trouble with delivery. My package got delivered several doors down the road, but that's hardly Tapzo's fault. I found setting up my profile a bit of a learning curve but once all set up, everything has worked well since. I've noticed that it can be difficult to tap the card on Android phones because you have to tap the card in a different place than you do on iPhones which is what I'm used to. Overall the card works well and has completely replaced my need for paper business cards.
