Laser Egg itself is quite sleek, but unfortunately(or fortunately if you have an extra adapter sitting around and do not want to contribute to more waste) does not come with an adapter, but it does come with a USB cord. The fact that it has a battery is quite nice compared to other air quality monitors. Keep in mind this model only measures temperature, humidity, and PM2.5 but NOT CO2 like other similar air quality monitors.
App Setup: Was relatively easy, but they pretty much require your phone location to be on for the app to work. This was a bottleneck that I had to resolve with support, and as I use the app I continue to notice this as well.
App Usage: the app sees to be kind of finicky, as sometimes it seems like it requires me to connect to the same wifi(which kind of loses the point of an app). Currently, it gives me the last updated time of my current time, but also says "NO DATA"
Measurements: I haven't had a chance to compare to another air quality monitor, but it does seem to rise properly when I am cooking.
Quite good !
