Review on Detector Tabletop Temperature Humidity Rechargeable by Melvin Goerge

1. "Instructions" is a joke. It says you can toggle the screen between the settings, but there's no info on what they're for or what they mean! 2. There is no "test alarm" and the little beep I heard when my CO2 was 1350ppm was so quiet that there was no way it could wake anyone up or be heard in another room of the house, even if it did he is not sleeping . 3. Holds a charge for a maximum of 2 days. There is no "Low Battery" signal - it just goes off. Whatever you want when your CO2 levels are as high as mine! 4. There is no phone number, website or email address for help in the package.5. I contacted the seller, they answered but did not help. I'm not sure if they understood there was a problem even though I explained it.6. Difficult to set up by hand as the tiny instruction manual is so short and vague. 7- It costs over $100! Save money and get a traditional CO2 alarm. Insurance requires you to be legally insured, but it will never count as such. People will die relying on this POC.
