we serviced our cash register for about 10 years, then switched to a webcass, in principle, there are no complaints about the work of the SC. But the fact that the law obliges you to subscribe to such services is gnawing at you. In 10 years, two devices have never broken, and we can change and clean the tape ourselves. As for the radio parts store, I have been a regular customer since the days when it was at the green bazaar, almost everything is there, the prices are good.
