We have been using unit and sonel devices for a long time, which are supplied by Pribortorg. The company's assortment mainly includes expensive devices, but we are always offered exactly what certainly solves our problem. I would only like the laboratory to work again, because it was much cheaper and faster to be trusted in it than in our CSMS.
I bought the Sonel LKZ 710 search engine from them, fell for advertising. They praised him very much. As a result, the expensive device works through a stump deck. The first one was generally defective, right out of the box. I also waited a couple of weeks for them to bring another one.
Wasted money.
The managers are excellent. There was a woman (elt40-50) who writes invoices, very rude. She needs to be re-educated or fired. Everything was fine that day, but then she appeared..
