Verified Purchase

Great product for helping to quickly determine room temperature. We use it in our nursery since it tends to be a different temp than rest of the house. And very accurate as it shows the same temperature as the baby monitor displays when it is on, and we accidentally placed a cool drink beside the Kelvin and it quickly flashed blue. Highly recommend.

Works Great

I really do like this product I plugged it in yesterday for the first time to test it out and see what I thought of it before putting it in the room with my youngest to try it before the baby arrives. It is nice that it shows the temperature at the top and the humidity and that the colors change to let you know if the room is too hot/too cold/just right. I have not tried the night light because that wasn't a feature I was interested in because I just wanted to use it to know if the room temperature was okay. This is a great product and will do exactly what you are expecting you just need to make sure that there is a plug in close to use it as it doesn't work unless it's plugged in and it can't be too close to a heat source otherwise it'll give you false readings. Otherwise, great product and I am going to continue to use it daily.

Cute and functional!

My daughter is almost four and has been sleeping in her own room for almost a year. She's had traditional outlet highlights and they have worked fine but this is so much cooler! It is not only a light but also displays the room temperature and tells you if it is too hot or too cold! You know if your child is in a comfortable sleeping temperature room as indicated by the color of the nightlight. If it's blue I know to turn the heat up a little since it's a colder month right now. It's nice to know the temperature of her room specifically since it's always a little cooler than the rest of the house. Still she tends to not sleep well in a room that is too warm so blue doesn't necessarily mean too cold for her. You can adjust it to your own preference. It is ready to use right out of the box. You simply plug in the cord so no set up. This would be great for an infant's room to judge how comfortable the temperature is. This is a great addition to any baby or toddler's room and would make a great gift! I love it!
