Did an order of TFT Plat 4 to Diamond 4, went through 4 boosters, it was went well, but took over a week to get done.
Did an order for Silver 2 to Gold 3, three boosters.
First booster for it was great, but they dropped the order after they said they'll continue it. Booster 2 tilted from Gold promos down to Silver 1 0 LP.
Booster 3 happened to be one of the TFT boosters that failed my order and finished the order at least.
I dont recommend ggboost at all.
I've had far more superior service on Boostroyal and I'm mainly on that site for champion masteries.
What a joke of a boosting site.
