Most domestic companies minimize losses through cheap labor. Even 20 years ago, the driver had to master the skills of a mechanic, because the distances to the nearest repair service are huge.
Then the machines were simpler, but today, without the help of a specialist from the service department, it is not always possible to understand which element of the mechanism has failed. In such conditions, the best solution is to get spare parts as soon as possible, but it is not easy to choose them. There is a problem of "imposed non-alternativeness" on the market: buyers have the opinion that there are only original products, and everything else is a fake.
This greatly limits the choice. Many customers are more suitable for high-quality "non-original" consumables, the purchase of which will not allow downtime, but because of stereotypes, they are afraid to purchase them.
