The Selphy prints high quality images quickly.
The operator (I usually use the app) is very user-friendly and has quickly here his routine.
I can give my printer to my pictures (a lot of photos: D) print directly at home and so avoid having to always go an extra in the drugstores. With regular and long term use it will save you time, money, and in my case also fuel.
The quality of the prints is better than in the drugstore, where it naturally arrives here on the quality of the photos, which are fed.
Note, however, that you have paper and printer cartridge purchase separately. One reason for the point deduction is not for me though.
