Ideal for printing wallet sized photos. The application he offers you to use, you don't even care. It's not user friendly, it needs to be updated before EVERY use (although I've already spent 15 minutes installing the update) and it just doesn't work. The DEVICE, on the other hand, performs quite well, although the photos get a bit dark (remember the classic Polaroid shots). I have a Google Pixel 3, so I select an image from my camera roll, apply a filter that brightens the image (almost blurry but without loss of detail), open image share options (usually used, if i send a picture to a text message) and press bluetooth. Make sure the device is turned on, then you can send a picture from your phone via Bluetooth without having to use the useless app. PRO TIP: These are wallet-sized photos. So if you try to print a large, detailed photo, be aware that only the center of the photo will print (the edges will be cropped). You can change this by taking a screenshot of your image, editing it to zoom out a bit, which creates a thick black border around the original image, and then printing. Because the photo is more centralized on your phone, it takes up more space when printed because the black edges are cropped.
