I purchased three of these units. I wanted to like them. The software is great, but the units are terrible. The readings are totally off - they are not accurate at all. I have professional o2 meters, ozone meters, VOC meters. These are SO far from accurate. I have set up two of them directly next to each other on the same table in my house for two months. The readers weren't even close.
I went back and forth with the company to talk to them and figure this out. They assured me they are accurate. Then I just got an email saying "Thanks to me they found a bug in their system and are working on a fix, so that ALL of the units are NOT accurate." How can people trust their lives or kids lives to a meter like this that is totally inaccurate? What if you lived in a place that had tons of VOC's and your meter says 10ppm.
This is terrible that they can get away with selling this. I got readings from two different uHoos, and one said VOC's of 5ppm and the other said 2050ppm; how is that even close?! They're on the same table! Trust me when I tell you - don't be fooled by the fancy software and packaging. The unit looks visually great, but it's NOT ACCURATE. Do not trust this.
Bottom Line: No, I would not recommend this to a friend
