As part of the baby bottle temperature measurement I have GloryTec ordered as a second thermometer for the relationship. We recently bought the SUNARTIS for us. First of all the Glory TEC measures langsamer.Dann much I wanted to see if the results are equal to at least and have both put in lukewarm water. But even with several attempts, the deviation was up to 4 (!!) degree. Since I usually only have a thermometer at home, I carried out the next measurement with all three. While the SUNARTIS and the thermometer came to almost the same result more GloryTec to whole 2 degrees off! The thermometer goes back directly. Especially when something sensitive like baby food but also for example when measuring low-temperature cooking such derogations are not acceptable in my opinion. Furthermore, I find the body of GloryTec quite cheap, simple plastic flat. If one measures to get probably will not get the idea that could measure it wrong. I advise the purchase from clear.
