Kelvin has a friendly and cute aesthetic so our son was very taken by him, and I’m sure would give 10/10 based only on ‘this looks fun to play with’! The temperature reading is reliable and accurate. My favourite feature is the humidity monitor at a glance I can see the temp and humidity percentage and that is real peace of mind, especially in a home that doesn’t have a home ventilation system, and being super conscious of how moisture in the air can affect the health of a growing baby. The light that emits from little Kelvin is soft, however we no longer use a night light, this is very easy to control and after switching off the light function you can still see the temp and humidity clearly on the display screen. Kelvin is a great option for the nursery and for baby number two we will trust Kelvin from day one.
