I got this because I wanted to stop guessing about the room for the grandkids and it does just that no fuss at all the display shows everything sharp and it's dead simple to use I keep it in the living room and it helps with comfort no more mold worries either VERY handy for a family like mine
- Pros: It tells the temperature and humidity right away very clearly and the screen is easy to read even for my old eyes delivery was quick and it feels light as a feather to handle
- Cons: Could be wrong if I put it near a heater or in the sun but that's on me not the gadget I suppose
