Super Rewind

Amateur photos and being in possession of a reflex, I admit that since I tried this device at the wedding of a friend, I was convinced of the practicality to take pictures in the simplest world with more backspin very friendly. For the unit price is not bad.
The small problem is that about 20 to 20 pictures, it's a bit expensive ... Especially the draw at the first cartridge will be partly spoiled by the lack of experience with the device ... it still remains a nice toy and accessible.
