A bit heavy
Crossfire tanks are almost an industry standard now. They have incredibly fast recharge rates and are extremely reliable. You almost can't go paintballing without seeing at least one Crossfire tank. The price is also very good.
I've had a couple or 3 Crossfire tanks and the regs have always worked flawlessly without any leaks. The one leak I have encountered came from a leaky fill nipple which was easy and cheap to replace and can happen to any tank.
The stock gauge is fairly large and easy to read. This can be a good and bad thing. Large can also get in the way of your wrist.
Crossfire regs are also not made with the lightest materials and are not the smallest regs on the market, so they can be a bit heavier and longer than some other products.
It's a great product at a great price. You really can't go wrong with a Crossfire tank.
