very nice easy to use

Great co2 monitor/controller, made well and very happy with my purchase

Love it should have bought it a long time ago. Very easy to install works great. Makes it so much easier to monitor. I don't have to check on it all the time.

I haven't really had an opportunity to use this yet beyond turning it on and looking at the features. For the features that the controller has compared to others on the market for similar pricing it appears to be a better controller because of the remote sensor. Time will tell. After I use it for awhile I will return and update my review as to its performance ease of use, reliability, etc.. I'm looking forward to having this tool in my employ.

This little co2 monitor was a great addition to my garden when I got it. It has helped me monitor the co2 levels for about a year, but then it just stopped working. The readings don't change, staying at 886ppm. I tried to contact the seller for a resolution, but did not receive a response. I need to get a new monitor, but I think this time I will spend the little extra money to get a more reliable brand.

This c02 controller is well worth the money! I would recommend to anyone. It was a lil difficult to figure out on my own but there is a YouTube video on how to operate it, now it’s one of the best tools I have. Perfect for a tent.

Exactly what was needed for the intended application.

If you are using CO2 in your grow room. Very accurate dispensing CO2.

Works great, as good as the more expensive ones.

Not accurate. Please see photo as to how it turns up.

Haven't had any issues after a couple months of use. Happy so far

Excellent for the price. Does what it’s supposed to.

Works as advertised. Made in the USA
