how much did it cost?
since it's a TT x0x, it probably won't have a bootloader afaik, which means that you won't be able to flash firmware
other than that, if it works - it works, you might wanna make tuning/calibration and/or some mods
if it doesn't work, you could still try to figure out what's wrong with it, and probably fix it
it's your choice, if you bought it banned, i'd say give it a try
