As stated, this is a very cheap, reliable but unprotected product. It measures the temperature fairly fast and I've tested it against other thermometers and it is reiliable. The only downside is that it cannot tolerate any water. I had water get onto it accidentaly twice and first the on-button stopped working correctly, however it was possible to turn it on after some tries. Turning it off didn't work however. Second time some LCD segments gave out, so the casing seems to be the only weak point for this product. (We used it to measure baby food temperature, and we'll buy a new one even with this flaw.)
