Super easy to use, and accurate. I bought this to have a 2nd thermometer for my 3.5 year old to leave at the grandparents house (who care for my daughter after school). I had a fairly expensive (over double the price of this one) forehead thermometer I received at my baby shower. This is much better, consistent, and appears accurate-I chose to keep this one at our home! I'm even considering buying a 2nd to replace the original. I prefer using the temporal reading, but love having the option for ear. Haven't had a need to take a room temp-but nice to know it's there if I need it. Versatile, reliable, and great price!
