I have been using this service for six months, and I am on the "Pro" plan, and honestly, I don't see a better offer on the market. I work as an individual entrepreneur on a patent, so the payment issue was particularly important for me. The team did a great job, helping me quickly set up an online cash register in just one day. I'm pleasantly surprised by the variety of services available for integration into the course: from Google Forms, which are much more convenient for data logistics than the built-in constructors, to streaming platforms and Wordwalls. The implementation of gaming mechanics happens smoothly thanks to exercises and elements like the "Dialogue Trainer." Overall, I am satisfied :) As for drawbacks, I would note that the "Text" element is not very convenient, and there are often issues with lists. It would also be great to have the ability to create at least drafts of courses on a tablet or smartphone.
