I stumbled upon this program online and tested it for two weeks. During this time, I was able to form my impressions, which I want to share. Pros: The interface is very convenient and intuitive. Setting up the keys was easy, as they provided instructions right at registration. The reasonable price is also a plus; the product is worth the money. Cons: Personally, I miss reminder notifications about the start of the tender (for example, "30 minutes until the tender starts"). Additionally, there is no mobile app, and a laptop is not always at hand. We are currently testing another system and will make a final decision soon.
