An excellent team of professionals, and especially from the testing center. Affordable prices for services, quick tests. I will note their anechoic chamber, a unique product in the Republic of Belarus. I have addressed these guys more than once and I will continue to address them.
Terms and prices are much better than the previous ones, there are almost never queues, polite service.
A temporary disadvantage is major repairs before entering the acceptance department - for now you need to enter from the main entrance, or drive around from behind through the transport checkpoint (with a pass statement).
