They have extremely honest reviews of paintball equipment. The reviews are from the viewpoint of players and point out both the good and bad things about the equipment. The "Dope" tech section contains a listing of the website, email address, and phone number for every manufacturer you can think of (and probably a few you never heard of). The articles and tech tips are extremely helpful.
More oriented toward an "international" crowd and tournament players. Also, the price is a bit on the high side at $6.50 an issue with only a stitched binding and 128 pages. PB2X is $3.95, perfect bound (hot melt glued), and had 160 pages. Part of the extra cost for PGI is due to the fact that it comes from Great Britain!
Overall, I would say this is a very good magazine. I am not a tournament player, and probably will not be playing in Europe any time soon. So, some of the magazine is just useless fluff to me. However, if you are into that style of play, I am sure that the magazine is helpful. Also, for the money, I would prefer a more durable binding, but that is just me.
If you are looking for good beneficial reviews of equipment, they have the best I have seen yet (other than PBReview)! The tech tips and play tips are first rate.
