Just bought the VIP trial to test the World of Warships cheat from Wallhax. To no big surprise - it works!
It's a bit pricey, and doesn't offer as much functionality as some of its competitors, but, supposedly, it's undetected. And having an undetected cheat is the main selling point.

Also, the Wallhax launcher is quite fancy!

Overall, I can recommend it if you don't mind the price.
