Battlelog

[leg24]

From my long research Battlelog is the best you'll get, and they don't have hidden charges from third party payments. A very nice thing is once you become familiar on Batllelog, you can be in and out in 1-2 mins. 

I have about 20 days of playing time on cold war and 10 days on warzone, so you guy's get the idea how the injections are very undetectable. (not saying to go shoot everyone through walls but it's possible to avoid a bans)
