It is developed by Evietron and no it is not comaptible with the C128. It is a nice cartridge and provides some cool features. It is not a 1541 emulator and is sort of what an EasyFlash would be like if it supported .D64 files. I am still working on a write up about it but of course lIfe got in the way so it's not done yet.
Edit: It is now C128 compat.

It seems to me that the price has gone down since it was first released, thus making it more tempting for me to buy.
Oh that's interesting. It wasn't C128 compatible when I bought it. I see from the version history C128 mode is under development and preliminary support was added to 1.2.5 so yeah looks like it does have C128 support.
The big selling point of the cartridge is its compatibility with various disk, tape, and cartridge images, like D64, D81, CRT, PRG, P00, .20, .40, .60, .a0, and more. Just drop the image(s) onto a microSD card and pop the card into the BackBit. You see the file(s) on a menu, you select the one you want, and it loads and runs. No Commodore calisthenics to get the computer to recognize the image type.
As mentioned above, the BackBit cartridge works with the VIC-20 with a special adapter that fits the BackBit into the adapter. Evie has a video that explains it at
