Question: I bought one of these in September 14. After 2 fills the pin failed and it will not hold air! What can you do for me?
Document: Bought this for paintball.Had it filled twice.Pin in the tank has failed.Won't work.Throw away and start over.Heard this is common with this tank!
I have 2 of these. One 2 months old and another over a year old.No leaks. No problems.Works great. Sweet price.I will buy more when the time comes.
Pin failed on first fill-up. Lucky I filled it within 30 days cuz that's all the warranty you get. Returned for credit.
Pin valve failed and leaked after 1st use. Will return to amazon. Very disappointing (and very dangerous). Do not buy
best co2 tank youre gonna get for this price arives in a timely manner, and is good to go man best co2 tank I ever bought.
just received the co2 paintball tank and have yet filled it. it came in the time frame stated. there a couple things that I am unhappy with. (1) the tank's hydo-test is out of date by well over a year. and (2) the upper lip is damaged. I hope that this doesn't cause a leak when connected to my gun. if it doesn't leak, will upgrade to three star rating.
this was exactly what I needed for my sodastream machine since a 14.5 oz replacement from Sodastream will cost about $15.00. This cost me  $22.00 at Amazon and I had it filled at Dick's sporting goods.for $4.00 for 200z CO2. You have to buy the adapter from Amazon($17.00) which also worked perfectly. So I spent $39.00 for the tank and adapter.
14.5oz cost $15.00, cost to refill tank $4.00 for 20oz.
The air tank was in great shape and arrived in less time than estimated. Filled it, used it and still lovin it.
Guerrilla Air 20oz CO2 Complete Paintball Tank no issues with the product seller or the packaging. Not to heavy for adults. Not for the little warriors
Answer: yes
