Be advised ..........
The Drift Stealth 2 let me down last year - wouldn't switch on and eventually went into the bin.
Bought a Drift HD720 and today it's gone TTTs up too & won't recognise any Micro SD card (inc. the one that was in) no matter what format type or size from 2 - 32 gb - more bin fodder - and you can only reinstall the OS from - you guessed it - the SD card, FFS
