Let's start with what I like so far (I've only had it a month. I like that it works, it gives you data that is somewhat accurate (with accuracy) are but like With any other detector there may be other things that increase the data I'm glad it detects every change in the air and I need to find out what it is For example my wife came home from work the other day went home and didn't wash her hair before she went to bed. The next morning the formaldehyde levels were off the charts because of the mothballs. And I thought it wasn't going to work, but her comment made me realize it. It was good. I like that I don't have a power adapter. Only a USB cable is included. Also, I was happy with it and wanted to rate it well until I got a letter in the mail offering me money only if I had one Write a 5 star review for the product. Now I do not trust this product unless I know the reviews were falsified. How many reviews have already been purchased? I think this company doesn't trust their product and they want to scam people. I'm disappointed. I doubt they'll even let me give my honest opinion here. Just take a look.
