The service is impressive, although it was not easy at first. The interface seems overloaded, there are many functions, and it's difficult to figure things out without video instructions. However, once I got into it, I realized that this is not just a bidder, but a full-fledged system for working with advertising, pricing, and SEO. I especially appreciate the ability to combine advertising data and Gem in one report. Support responds, but sometimes I wish their reactions were a bit faster.
