Price: $18.95
Pros: It does work and very convenient
Cons: Buy a Loot of cartridges..takes about 6 cartridges per keg
Recommended? Yes

Comments: I used this at my party Saturday night..It did work but I got tired of constantly having to change out the cartridges...seemed like every 15 minutes it needed a new one. I finally just brought my 5# c02 tank out.

I would recommend this for mobile/camping but not for backyard, too much of a PITA to swap the cartridges.

Price: $19.95
Pros: Sturdy ,well made,easy to operate
Cons: Needs additional parts not included.
Recommended? Yes

Comments: I bought this to take on a road trip to Colorado. Had 4 cornies fully charged and didn't want to lug a big co2 tank with all the other stuff we had. I went through about 9 cartigages for dispensing-only on 4 kegs. It worked great.

Price: $18.00
Pros: Handy, Quick, Easy to use
Cons: Somewhat expensive, not complete kit
Recommended? Yes

Comments: This is what you ned to take your keg on the road. To be fully functional however, a beer line out, picnic faucet would be assumed as well as the quick disconnect for the gas in that this device attaches too. Most kegger folks have this stuff allready but is is technically a pre-requisite.
Just got mine today and don't have a handle on how much CO2 is really in there, or how long it lasts. Really it would be best to just use it to top off pressure when you have already filled up with CO2 at home from your main tank.
