Review: 10 Stars! - 10 stars! I can't believe this unit can be this great of a deal, but it really does seem to be. Just got it, and out of the box it's completely accurate (within margins of all the meters in general), and is working perfectly so far. It was professionally packaged for shipment and doesn't feel like a cheap unit. If the build quality stands up and this unit lasts, it's going to be among the best purchases of mine to date. Edit: Unit is still working perfectly, and has doubled the life of my Co2 tank versus just using a regulator and timer. Only having to go once a month for refills now, means this unit will pay for itself in about 8 months factoring the costs of the Co2 and the gas driving. Update: It's been about 4 months since purchase and the unit is still working without any issues. I couldn't be happier at this point, and would buy another one without worry. I'll try and update towards the year mark, or sooner if there is an issue, which I don't foresee. 2+ Years update - Still working just fine. Getting ready to purchase another unit for another room and figured I'd update with news of the longevity. 3+ Years Update - Just as good as the day I bought them. 4 Years Update - The only problem I have had is that these are not in stock so I can't buy another one...
Review: Works Great - Works great. Always wondered what my PPM levels were without CO2 supplementation. Well, starts around 600 PPM and dips below 400 PPM. Now I have this I can not only monitor my levels but I added a 20lb CO2 tank of course. I keep my levels at 1100 PPM and since I bought this it has been 3 weeks. I have seen a major change in my plants growth. Girth has increased and I have needed to up my room temperature from 75F to 80F and nutrients from 0.6 EC to 0.9EC . I noticed a 200 PPM drop in my nutrient solution over a 2 day period. Usually I only see drops like this over a week period and when in transition (ie: week 2 of flower). Update: the newer model has a high and low setting. I got the newer one when I ordered another one a year later. Update: Since using this meter I have been able to monitor my CO2 supplementation and loss. It has been a money saver. My rooms are sealed now and I can get a 20lb bottle to last 2-3 weeks at 1200ppm. I have doubled my yield after tweaking my nutrients to coincide with the increased metabolism from my CO2 supplementation. $13 worth of CO2 every 2 weeks. Best $78 per grow spent ever. No bottled nutrient will give you the results CO2 will.

### ⭐⭐⭐⭐⭐ Best bang for you buck
*by C***Y on March 10, 2017*

This meter was purchased to run my autopilot co2 generator. And I will tell you it exceeds my expectations. It's accurate and keeps my 18x90 greenhouse @ 1200 ppm. The meter can be used to run a generator or an exhaust fan to keep co2 from reaching high levels. Very easy to setup and use. 10 minutes and I was up and running. I'm going to purchase more for my other greenhouses and would highly recommend this to anyone needing to add co2 and precisely control it for a small grow to a large grow. A PLUS
