The delivery has been some time in coming. Otherwise, I can not write anything, which would evaluate the product badly. I have ordered the thermometer equal 2x and was very impressed that the sensors have only 0.01 ° C difference. What could you do better? In my PC to have a temperature of -20 ° C, I can confidently exclude and that will be in most of the case. Here the Scala should have begun from 0 ° C. But for the of use is very flexible, as long as a current connection exists. The reaction of the altered Temeperaturen (in my case the graphics card) is a bit slow. Otherwise, I may make a recommendation because the installation done quickly and easily and is stylishly appealing.
