I had an email from Carista earlier today offering a 30% discount on their Carista Evo OBD2 reader (here: Carista EVO: Next Level OBD2 Bluetooth Scanner). Has anybody already got one please and, if so, what's the opinion? I'm asking as I'm tempted but before splashing the cash I'm wondering whether it offers any additional facilities on a T6 over the original (other than speed of connection and communication with whatever app you use which in itself might just make it worth buying even though it is quite a it more than the original, but not that much after the discount). If anybody is interested, the discount code is CARISTAEVO30.
