After having to hunt down a new battery all over town to replace the batterythat came with it because it was installed already and dead I got it . Once I got it to work it preformed fine. Quick forhead reading for the baby. And you can remove the forhead cap to make it an ear probe. The display screen is easy to read. There was also great customer service when dealing with the dead prouduct. #rankboosterreveiw #Sponsored #Topoint https://www.amazon.com/Infrared-Thermometer-Topoint-Temperature-Portable/dp/B0734QQYBV
