I've first purchased the Advantage Pack Trial for only 1.50 dollars a few days ago which offers all the hacks that Virtual-Advantage provides for trying them for 24 hours, which was enough time to make my decision and buy the 1 month Advantage Pack, and so far I'm pleased.

To start off, you need to be cautious and aware of the game you are hacking on in order to not get banned. Once you purchase, you get instant access to the hacks, and you can go anytime on Teamspeak 3 to get yourself started, like I have.
There are always people on Teamspeak, and if you just ask them or poke them, they'll help you until they get your problems/concerns solved.

The first cheat that I tried out was APB: Reloaded, it was quite great and I must say FairFight is a joke for me. I've been "rage hacking" I would say with ESP, Aimbot, 2D Radar and all such, been called out lots of times, but for 3 days I'm still not banned.
It has a lot of settings for your preferences, whether it's for rage hacking with aimbot, slowly snapping around enemies, just having that soft aim, or ESP.
I would rate it 10 overpowered ARMAS guns out of 10 WASP members complaining.

The second cheat I think was Insurgency, which is decent. The menu might be slightly difficult to navigate through, because you need to pause the game to have a cursor and then you can easily navigate through. Personally I've only used ESP and I've got that going for me. I would rate it 9.9 people yelling religious things at round end out of 10 teamkillers, and because the ESP slightly flickers a bit but it doesn't bother me that much.

The other hack I tried was for Counter-Strike: Global Offensive, the menu is a bit tricky at first and figuring out the features as well, but you can go on Teamspeak anytime and ask a qualified person to help you out. So far I've played 5 competitive matches, 2 cooldowns for winning matches too fast/VALVe employees checking my demos? and I've been called out 3 times but I'm still ♫ Havin' a good time! ♫.
Other hacks, I haven't just yet tried them all out, but I plan to. To be honest, I've only paid 1.50 dollars and I've recieved about 5 hours of constant support until I got set up on my first day, and that is less than I give my ISP and they don't even help that much. Clearly I had to get the 1 month subscription, as I was very satisfied with my first day.
Overall, I rate the Advantage Pack ( so far ) 10 0.03 emoticons on the market out of 10 boosting services in LEM ranks ( I've found 2 so far, but that's not anyone's fault ).
If you're planning to buy any of these hacks and looking for any last minute researching or opinions, then you should go ahead if you truly want that virtual advantage!
