a tight connector at the cable on the side of the mouse with an individual profile (you can’t turn on the left one), after 2 months of operation it ordered a long life (cable) - no one answers the phones from the raiser site during working hours. when they answered, it turned out that you can’t buy a cable separately (in the 2022), with a guarantee, too, not to them, but to the seller (s - service, p - support). in total, I didn’t succeed in restoring the device to a hot work at my own expense, I’ll have to contact the service and rely on the responsiveness and efficiency of the seller. in the worst case, I will get my hands on a dead device worth 7k (because the cable cannot be bought separately).
