Comparing with my old thermometer which I could not find a replacement battery, this one is not user-friendly designed:
.Display area is quite small and hence the digits;
.Protected only by a sleeve (or IMO, a half-case...cutting cost?);
.Slow reading and there is no alarm sound once the reading is ready; and if you wait for too long, the display is gone and you have to press the button to "recall" it.
I give it a 2-star since the reading seems to be accurate and some one might like its compact size. Random colors available too (mine is greenish).
I then ordered the other thermometer with a much popular rating and it has every feature that this one missed. However since well.ca does not take back product with an opened package, I will keep Bios as a backup.
