I purched this thermometer over 5 years ago (maybe more) and it just died on me. I never had any problems up to this point. I think it lasted a long time for the price, considering I have used it on my own 3 children and on my daycare children. I will be buying a new one. I would recommend this to anyone looking for an ear thermometer that is quick and easy to use.Get more detail about Braun Thermoscan Ear Thermometer with ExacTemp Technology.
