Have the unit a few days now, but the outside temperature is compared to 2 other devices whose displays up to 0.2 degrees C are equal to ca. 2 degrees appears too high. Too bad that you can save more at the wrong end. For higher precision it would be a worthwhile instrument. This is the internal temperature even can set the expense of another option is also a some shortcoming. But one could eigenlich the alarm function (alarm) in my opinion, is probably used by only a few, leave. Too bad a few components with slightly tighter tolerances that ensure only a few euros would account for the price, a really good device would certainly arise.
