Here’s what consumers have asked with answers from Platinmods staff and previous consumers.
Totally legit. Most of their "products" are available for free anyway, so you can have an taste of how good it can be before going VIP. Which is cheap considering you got 3 licenses that resets each months by themselves. The support is also really nice and helpful and they won't mind helping you out, VIP or not, they do care.
Fastest service, broader games supported (and "harder" games) as well as safer usage. And just the fastest update out there. Nearly feels like self-updating considering how fast it is.
