Question: In my research it says the life of these tanks is 15 years. If ordered what is the manufacture date? I understand the  certified date is for 5 years
Document: I highly reccomend the pure energy N2 tank to anyone who plays paintball with their own gun. Why? You extend the life of your gun and get a far more consistent shot. I find that the pure energy tanks offer years of reliable service and are the choice of many paintball fields on their rental guns. The carbon fiber wrap allows you to get a larger tank without adding weight and the 5 year hydro retest date allows you to have a longer worry free playing time. Worth every penney you will pay.
Great tank, the quality is great, I got this months tank date, so it is good for a full three years from this month. I spoke to the seller about the logo difference & she told me that there was a buy out from one company to the other, so a different logo is used, but she sent me the latest dated tank and that was great.
I was looking for a new tanks and came across this. The price was the best that I found in stores and on line so I bought it. Very good quality. Love using it.
I hate all the haters who think this product is junk. Your wrong! If you don't throw it on the ground, drop or do anything to damage it, it will work as intended. When I received it, it was empty as said in the description and I pumped it up with my Benjamin hand pump that I also purchased and had many people say that pumping up these tanks is too hard and is a waste of time.
This tank is amazing. It's perfect sized for me(I'm 5'4" and 111lb. ), and it is extremely lightweight. I prefer this tank over cheaper aluminum and steel tanks because of it's size and lightness. It weighs about the same as a 20 oz. CO2 tank or a 48ci aluminum tank. I used to use CO2, but then I had a bad experience with it on a cold and rainy day in the woods. (paintballs stuck in the barrel, busted o-rings, etc.)
I play recreational paintball and to give you an idea as to humidity/weather conditions, I play in Houston, Texas. First off the tank that is in the Amazon.com picture isn't the same as the one that I received. After going to the main company's website I found out that the picture is incorrect and I did in fact get the tank with the specs I ordered. The one I got in the mail looks fine. It doesn't have the radioactive graphic. It has an Empire graphic instead.
Anyway, I reccomend this tank all players, new and old.
I just used this yesterday and had absolutely no problems at all with this tank. But the tank in the picture looks different than the one they sent me.
I used this tank for the first time yesterday. Its a good tank for a great price. Go get one!! !
I guess If your weak and lazy then you wouldn't be able to but it works fine for me.GET THIS TANK! DON'T LISTEN TO DUMB PEOPLE ON HERE!
