Pretty easy to setup and get loading.
Prev and Next disk buttons are conveniently placed. LEDs provide a quick indication of what's going on.
A recommended addition overall if you down have a lot of original carts or working datasette.
The only thing that I find inconvenient is the location of the SD card of which tends to be obscured by the cable. This makes it a little fiddly to remove/insert the SD card i.e. to load a new program etc. Not a show-stopper though.
