Picked up 2 accounts for playing with lower ranked friends. Both worked perfectly fine. You get access almost immediately after paying.
Only small complaint was one account had 5 days cooldown before I could change the name. But whatever, doesn't affect actually playing the game.
Bought a LoL smurf account here - super smooth transaction. Account was exactly as advertised and delivery was instant. Would recommend this seller if you're looking for a reliable place to get a smurf account.
