Bought a pilot CM boost with these guys and do not regret it.
At first I was very hesitant to do it, sharing my account info and all that, but I still decided to do it as it was very cheap. They finished in about 2-3 hours and I was able to watch the progress on twitch if I wanted to. They also provided helpful instructions so that you can revert any UI changes that may have happened.
Overall they did an awesome job and I would definitely use their service again in the future
