Gan Smart TImer
Very good product but it is overpriced and they don't provide batteries it is not worth the price because if you buy a cube with it suppose the gan 11 m duo 4000 plus 3000 is 7000 that's very expensive if they provided at least 2 or 3 sets of batteries it would be worth it but very good product it shows last five solves and even AO5 very good product but not worth its price
