This tank is lighter than the older ones because the reg is now made of aluminum instead of steel. Has a good recharge rate. You don't need a drop to use this tank either.
The on and off valve is hard to open or close when the tank is filled to 2500 PSI. More like a pain in the fingers
This is no cheap HPA. I believe it is worth the money if you can afford it. All in all it is a good tank and a good company. All I can say it is more reliable than an Angel Air out of the box(seen 3 brand new Airs leak out of the box)
