I tried odering Game Boy dumping devices for a while now, but they were either not available, too expensive or my last try ended in getting messed with by the seller and the delivery service.
With this device, it finally worked out, and the device itself so far perfectly did what it's advertised for. I could easily dump the pictures from the Game Boy camera. Aside from saving photos from a deceased friend, I want to keep using this thing and having those pictures not trapped within this device.
I didn't do much else with it, but seems like you need to get used to the management of the pictures, since the device doesn't erase the photos from the camera, you still need to do this manually, and the device seems to keep previously copied photos in memory and show them to you, even though they are not there on the camera anymore. It's a little odd behaviour, but you can treat it as a backup.
So far, nothing for me to complain about, hopefully this thing will stay in working condition for many years to come.
