At first I had thought this device was good. It was always imprecise (inconsistent results, taking 4 readings over the course of a minute gives readings which vary by over a full degree), but it appeared to be accurate (testing several times and averaging them gave a similar number to another under-the-tongue thermometer).Then later, I actually got a fever. Testing with my other thermometer proved it, but this one entirely failed to register the fever. It was measuring several degrees beneath both my other thermometer as well as subjective "feel" of having a fever.Testing it again a few weeks later, once my fever had gone away, has returned to the "imprecise but accurate temperature" status.Overall I have very little faith in this device.
