Full review and unboxing of the AI8000 with lots of test clips and 20% discount codes Normal price £50 but 20% discount codes = £40! And comes with two batteries, external charger, wrist remote and the other usual accessories. Good value for money. I don't know what the sensor is, but 4K is claimed? For anyone who really wants or needs it. The 2.7k is good. Very good review of the AI8000 with lots of test clips and 20% discount codes
