First of all, I'm new to this site and expected nothing. But the looks of the site and the hacks surpriced me positively:

Easy menu, one of the best I've seen so far. Got my settings right under a minute. 10/10
It's possible to make the silent aim really realistic, some forum posts help me too. 10/10

The possibility to purchase a three day trial is perfect for me. I'm only playing on weekends, so three days are enough for a quick fun.
So overall, great experience. Would definitely recommend it!
