I just recently used SimpleBoost's leveling services, so I can tell you a little about my experience. Let me start by saying that I've always been skeptical about such services. Firstly, there are always concerns about the security of your account, because someone can simply buy your data or get into it in some other way. Secondly, I was worried that it would take away some of the fun from the game - farming and leveling have always been an important part of my WoW experience. When I decided to give it a try, the first thing I did was look for reviews. SimpleBoost seemed fairly transparent to me, they had security guarantees, and the site overall left an impression of a professional. I placed an order for leveling one of my characters, choosing a service that included completing several difficult raids and leveling up. By the way, what I liked was that I could choose a convenient time for me, and the leveling took place without my participation - I continued to play my character as usual, and the customer did the rest. The process itself didn't take long - I chose the standard plan, which promised to deliver the results within 2-3 days. The guys really did it quickly, and within 24 hours I noticed that my character had risen several levels, and the raids were completed. At the same time, I didn't have to worry about security - they offered to use additional measures to protect my account, such as two-factor authentication, to minimize the risks.
