Great Quality! Think I'll Get A 2nd One for RVing

This is very nice. I had wanted something like this, and the quality for the price is amazing. I was concerned about CO2, and the temp and humidity are a real bonus. It has proved interesting as I have taken it to all the rooms plus the basement, and checked different times of the day. Thankfully will always fall at least "normal". Hope to use it RVing too!
