II've decided to purchase a boost and reach my diamond dream so I went with ggboost.com. I was very surprised, my order was picked on within minutes and my booster was quite friendly.
I've ordered a platinum 3 - diamond 5 duoq boost.
Good things:
Very good player
Fast start of boost
Booster was coaching me at the same time:)
He was very funny and made it easy
As for the bad sides, there are pretty much none. Maybe a slightly pricey and a few hours longer than they advertise but It's nothing that makes a change.
Overall 5/5 - would recommend to anyone in need for a boost like me.
