This is me using RoE cheat very freshly, so don't take it too serious and into consideration, as i haven't had a chance to use it for longer that 4-5 hours.

All functions work perfectly fine, there aren't any issues. Its more or less a cheat that you buy and hop into a game - doesn't require any system modifications etc. Worked for me once i bought, downloaded and worked; never crashed. 

ESP - 10/10 works perfectly fine, no fps drops recorded for my case.

Aimbot - As an aimbot overall it works 10/10. As an aimbot for RoE works 5/10 the reasoning behind this is that it doesn't compensate for the distance of enemy player, this means that if youre 200m away from someone thats moving sideways from you, there's literally a 1 to a 1000 chance you'll hit him - basically someone either has to run away from you or towards you in a straightish line or be stationary for the aimbot to work. Although saying this, it works just fine and is playable if you know how to use it properly.

FOV & Smooth works fine, i've found my sweet spot in the setting where the aimbot is very overpowered but looks legit at the same time.

Working around & with the menu: Menu is simple & easy to understand, there's no way you can do somethig wrong within it as everything is simple. You've got your tabs for esp, aimbot and more and all options are easy to use & understand.

In conclusion this is a fun little tool to use yet requires some more work to be really top notch (mainly aimbot distance compensation) but saying this, its a very cheap and affordable tool that will provide a win in a game without any issues. 

Hopefully this helps some of you that are thinking about purchasing!

Will try to add more info as im still using it.
