I personally have used wallhax since 2015 (with some breaks in between) - Great Package for a Great Price, developement on features may be slow sometimes, but bugfixes aswell as updates are usually done quickly.
The overall support if problems occur is usually pretty fast - Community wise (if there are ideas on how to fix it) aswell as Admin wise (if there are bigger problems).

Overall I give wallhax a 9.6/10
