Regardless of which product you intend to buy, you'll have the chance to talk to a welcoming, warm and friendly community who I'm sure will be more than happy to help you out before you spend your money, so that you'll know what you're doing - Don't be afraid to ask question, if this is your first time, setting up the cheats can seem difficult, but it's like riding a bike, I assure you :D
I encourage you to browse the forums, see for yourself what is offered here :D
So far, I've purchased the Ring of Elysium cheats. These include a fully functioning 2D radar, ESP which features customizable colours with a 2D bounding box and skeleton, complete with a Bone Aimbot, so you can pick exactly where you want to target on your opponent!
It is completely undetected, you'll only find yourself banned if you take things too far, like rage hacking - But if you keep things chill and play as if you're legit, let enemies come to you and don't get insane amounts of kills compared to your normal? You'll be perfectly okay :D
There's a community here built on trust, that trust allows PA to be as secure as it can be with its cheats, to ensure no one gets banned. There is no better provider in my opinion, the service is unrivalled.
