Co2 Monitor...

Has anyone used one of these Co2 monitors? I'm thinking of buying one. It connects to pc for data analysis, and only £60/$90

Ive never used that one but i have a titan controls atlas 1 co2 controller and it works great. I use a burner though, I'm assuming this is for a tank. I would be wary with the price on this because all of titans co2 controllers are $300 plus and they are great quality. Been using their stuff for years with no problems.

Thanks...going to continue research
