Pros Can connect to your phone* via Bluetooth
Can connect to a pictBridge camera (wired)
No ink cartridges necessary
Prints come out fairly quickly
Cons Print quality is mediocre at best
Will not connect to iPhone or iPad unless it is jail broken
Summary This little thing is fairly fun to play with. It costs about $15 and has Bluetooth capabilities. The photos that come out of it are not that impressive, but they are usable. The prints come out on 2"x3" propriatery Polaroid "ZINK" paper. Also, you can remove the backing and use them as stickers if you wish.
Unfortunately, this little thing cannot be used with an iPhone or iPad unless they are jail broken. This is not Polaroids fault, but more the apple closed box mentality. I had to use my 4 year old LG to test it out. I had absolutely no problems connecting to the device.
All in all, for around $15, this device is worth the money and the refill photo paper is not all that expensive.
