Comments: The product works good as far as telling how much co2 is in the tank, but I had to put a small dab of silicone on the suchion cup to keep it stable and not fall to the bottom of the tank Yes, I would recommend this product to my friends.

Azoo CO2 Indicator by STEVEN D WILLIAMS

Experience Level: Intermediate

Posted on 2/13/2008 from SANDY, OR UNITED STATES

Comments: It seems to work very well. It is less expensive than atlease one other and no membrane. Just don't fill it too much. The instructions are on the box but the contrast is poor -- red background with black text. Yes, I would recommend this product to my friends.
