I just received my two devices and am excited to use them. To register, you must submit a review; so far, so good. I plan to plug everything in once the registration is completed. I purchased two Miko units; they were supposed to be the same, but one is white with a hand strap, and the other is gray without a strap.
Great air purifier! I love the quietness of the device while running and the ability to control the device wirelessly on your phone using the app. I had some trouble connecting the device to my home WiFi but eventually got it connected. Great looking purifier which does not look out of place in any room.
