Can't say I've used their field, just their proshop once.
As stated above, I can't say I've played at the adrenaline field, but definitely have been to their proshop. I was there with my brother because he was looking around for his first paintball marker. When I was there, first thing I noticed was the very understocked shop. It had few of a lot of things. The markers that were there, only about half were for sale, the rest were display. The person that was helping us, did not seem very educated in paintball, and was a little rude to my brother when he tested a gun out by commenting "he shoots like a girl."
I'd imagine that the Adrenaline field would have all the same safety rules as Flagswipe's field and that their refs would have at least some experience in paintball. Alas, I cannot give an accurate rating since i haven't played there, so to be generous, I'll give them a 5/10 for the field. As for the proshop, I was actually expecting the employee to be more helpful, not as rude and not pressure us into a sale to make him look good
