Overall, the service is decent, but it has its drawbacks. Firstly, it is paid. Of course, 30 rubles for 100 checks may seem like a small amount, but when it comes to thousands of checks, the total becomes significant. Secondly, I sometimes experience issues with the service freezing, and I have to wait. Thirdly, you cannot test the service without registration. Moreover, the free 20 checks are only available after topping up your balance. Fourthly, analyzing the level of competition can only be done without considering the region. Despite all these nuances, I occasionally use Mutagen, but I can't rate it higher than 4. I hope for further development of the project and request that discounts for regular customers be considered.
