Customer Reviews

Totsally awesome!
Love this co2 kit. Cant wait to have space for a 5lb cylinder so I can use it on that. That to me was a huge bonus without having to buy a new regulator. One regulator that fits everything. Very well made.
-
This nano co2 kit is amazing.
After lots of research and many of recommendations this kit checked all the boxes. Steady on week 6 now and loving it. All my friends ask me about it since it’s so visible. It looks terrific and functions phenomenally. GLA customer service was second to none.

Super nice kit.
Very happy with my kit. I emailed them and they sent me a photo of this regulator on every cylinder type. They also have a cool manifold option available but I didn’t see it listed, so I emailed them to inquire and said it should be up within a few days. Good quality stuff and customer service is really above anything I’ve encountered.

Super nice kit for my nano tank.
Very robust and heavy duty and yet compact. I like that it feels substantial and not like a tiny toy. More so I like that it can fit any cylinder type. Very good solenoid and metering to this is a bonus.
