Service is a fraud, PLEASE Do Not Use.
They will add the currency you purchased, but the no ban add is a LIE. I added gems to Eternium and I got banned, the game support itself confirmed it as they saw a third party app add the currency. Yes, it is my fault for using services like this, but they should not have a no ban guaranteed which is a LIE. Please do not use unless you want to lose your game profile and either start again or retire from said game. SCAM service, they replied here because of bad review but I NEVER got a reply from them directly or any offer to fix problem, its already been a few days.
