I liked the tour, many thanks to the guide Olga. It is very informative and not too long. The factory's products are impressive. I definitely recommend you to visit. The only caveat ... If you plan to buy souvenirs, then do it right at the store where you pay for the tour, you will not return there, and there is less choice in the second store.
The museum is great. Everything is done inside is very informative. All miniature units of manufactured equipment, including Soviet times, are collected. According to the photo, you can live a short history of the formation of the enterprise. The review also received state awards and not only, there are symbolic gifts from other countries with which the organization cooperates. It is definitely worth a visit. And keeping up with the times, I would like to suggest making a virtual room where you can personally participate in the process of creating career equipment, or go back in time and see the stages of formation of the flagship of our country.
The place is a must-visit, if possible.
Taking pictures next to a 450-ton car, and even more so, taking a ride along the test track (even if not driving), seeing a new mining dump truck coming at you from the assembly line - all this is definitely worth the money and time spent on the tour.
Nevertheless, in my opinion, the first part of the tour (where the museum is) is a bit boring. Think about adding some interactivity. For example:
1. "Virtual driving trip", where one could climb into an analog of a Belaz cabin and, using VR, take a ride in one of the coal mines.
2. A mock-up of the assembly line, where you could see from the outside how everything works (during a real tour of the workshop, everything is too fast).
