Review on SereneLife PICKIT21RD Red: Portable Instant Mobile Photo Printer - Wireless Color Picture Printing for Apple iPhone, iPad, Android Smartphone Camera - Mini Compact Pocket Size - Perfect for Easy Travel by Richard Alemayehu

Instructions aren't the best, but installation is easy and doesn't bother. First I charged the printer. After that I installed the Android app. It was easy enough to find on the App Store and figure out how to use it. To turn on the printer you need to press and hold the small round indentation on the side which is obviously the power button. Once activated, it should try to find your phone. This worked fine for me. If NFC isn't enabled, just enable it and try again. It looks like there's a way to get it to work with Wi-Fi, but I haven't tried it. Once connected, printing becomes a breeze. The printing is fast enough and the quality is good. The cartridge contains paper and ink for 10 photos. Removing and replacing the cartridge is very easy. One side of the printer opens and the cartridge simply pops out. I am attaching a photo of an opened printer and cartridge.
