Crappy rental masks...really awful unless you use anti-fog spray, and even then they're not that great.
A5 w/E-grip...The gun never works! That's fun. Piece of crap.
+Huge field of vision
+Soft material=more bounces
+Easy to clean
-Not a lot of neck/chin protection (very minor issue)
About a year and a few months ago, I purchased a Tippmann A5 with an e-grip, a brand new J&J barrel, a 72/3000 HPA tank, and the VForce Profiler mask I am writing this review for. The gun is a piece of crap and never works (even after sending it to Tippmann like 3 times), but that is another story. I completely regret all the purchases I made that day--all of them but the Profiler. It is quite simply one of the best masks you can buy when you're playing paintball.
When it comes to its strengths, I don't even know where to start. First thing's first: when you first put the mask on, you will notice that it is ridiculously comfortable. The foam is soft and never feels pressuring on the face. Even if you're sweating all over the place, it really feels great. The rest of the mask never gets in the way of your face, so you barely feel it. It's really fantastic, you barely even feel like you're wearing anything, even though you know you have plenty of facial protection. The next thing you will notice when you put on the mask is its incredible field of vision. The lens is rather large, and has a curved shape to allow you to see out of all angles. It's really fantastic; there has never been a time when I had any issues with this mask due to a lack of vision. Again, like with the comfort, it's as if you were not even wearing a mask at all. Another great and much appreciated feature of this mask is the soft material used for the side of the face, the mouth area, and the visor. Though certain parts of the mask are hard plastic (the areas surrounding the mouth, among others), the soft parts really come in handy at times. There have been numerous times when I'll get shot around the ear, and still be in the game, or--and this one is even more common--when I'll get shot in the visor area and it will just deflect right off. It's not a huge feature, but it is a little something that you will come to appreciate. When you do actually get hit in the mask and it breaks, you have no need to worry. It's ridiculously easy to clean. If you want to take the mask apart, you can easily do this in no more than a minute or so. That way, between rounds you can effortlessly take out the lens, thoroughly wash it and dry it, reassemble the mask, and get back on the field in time for the next round. It's just that easy.
But of course, there is one positive I have not even mentioned yet, and that is that the mask will never fog on you. I don't care what you do, you can probably shove a kettle of boiling steaming water in your mask, and it still won't fog. Totally brilliant. Here's an example: I was playing in rain just recently, when the humidity was over 70%. I was breathing heavy (as many adrenaline-pumped paintball players do on the field), and coupled with this humidity, all of my friends who had rental masks were complaining about how they could hardly see anything. I, on the other hand, had totally, completely clear vision. Given the circumstances, it was remarkable. Simply put, unless you use harsh chemicals on the mask (by the way, never use anything to clean thermal masks like these but water, I learned this the hard way) and your anti-fog starts to peels off (time to replace the lens), this mask will not fog up. Period. After a year of use, I have had no fogging issues whatsoever. It can't stress this enough, it's really that good.
But of course there are weaknesses. First thing is that some may find that the chin protection is not the best. The mask does not come down very far to protect the lower chin, but this is all done in the name of comfort. It's really not a big deal. The only legitimate problem with this mask is the price. At around $60, it's not the cheapest mask on the market. But I guarantee you this: if you make the investment, you will not regret it. You can buy a $30 non-thermal crapmask and have problems out the butt, or you can bite the bullet and buy this one and never have a problem with your vision again. To me the choice is simple, because in reality, the mask is the most important piece of equipment you can buy for paintball. If you can't see what you're shooting, what good will a $3000 gun do you?
So in short, this is probably the best paintball mask ever. Buy it now.
It's about as close to perfect as you're going to get. Buy it now.
