I have been using the VeSync for a few days in my bedroom and can very confidently say that I have felt a change in the air quality as I share the house with two cats. The best part I love about the product is how quiet it is. The control display is very easy to use and very nice looking as well. The setup itself was very easy on the phone app however I am noticing an issue with getting notification but I believe that is due to android and not the app itself. Just recently I have set a schedule based on the times I will be away or home and it has been working great. Looking at the product build quality, I am very hopeful this will last me quite some time !
