I've been playing PUBG on and off since it came out. Every time I get back to gaming, I ALWAYS sub to IZI.
The admins are always checking up with the different complaints and updates and even have other people helping them out with the more mundane things.
I am completely sure that the admins number one priority is customer safety. They won't launch a faulty products 1 hour after the game was updated just for peolpe to stop complaining, they will make absolutely sure that the product they launch is safe for everyone to use.
Menu might not me be your typical user friendly menu, but then again, IZI is not your typical cheat. Using IZI won't get you detected, and in order to have that benefit you must deal with some simple things that you might not completely like, but trust me, you will get used to it and you will love it.
In the end, if you want to be completely undetected you must sacrifice some things, and as said before, IZI will always focus on customer safety. So if you want to play undetected, use main accounts, buy in game items and not lose your account after one game with some other hack, sub to IZI.
