I sell stationery on Ozon and use SellerFox as one of the most convenient services. I like its structure, the quality of the information provided about myself and my competitors, as well as the well-organized presets. Currently, I am considering the possibility of expanding to WB, and during my analysis, I noticed that SellerFox's page loading is not very fast. I will deduct one point for this, but overall I am satisfied with the service.
