I've come across sites that looked attractive several times before, but actually turned out to be inconvenient and confusing, so now I'm taking a much more careful approach to choosing. Even then, I began to look closely at because it is important to me that the interface is logical, and the information is open and accessible without hidden sections. I study the structure of the site in detail, check the availability of the license, read the terms and conditions, and only after that I conclude about transparency and reliability.
