It does what it needs to do.With only one button, there is not much can go wrong did, right? HOWEVER, It's Still a bit tricky Because You tend to forget how oft you have to press one button did, in Particular When You Are awfully SICK and running a fever. For example: 1. Push button to turn on, stick device in mouth right away? Push again or shall I now wait for the beep? 2. Push button to turn on, push again to start measurement device ?, stick in mouth and wait for beep? Since it can take up to a couple of minutes for the beep to come, it makes you uncertain what's going on and is Actually Whether measuring. I recommend to keep one eye on the screen (use a mirror if needed) so you can monitor the measuring process for peace of mind.
It would be helpful if They printed the required steps on the thermometer itself. For that, I withdraw one star.
