Product review (3 stars): So far so good
I bought two, even after reading the negative review. The instructions are horrible. I read the answers to the questions here on Amazon to set the time. Mine do not have the two buttons on the back as shown in the picture. The C/F button is under one of the legs. The is no reset button and the is no hole for a rest as described in some of the reviews. I reset it by removing the battery and installing it again. I sat the two units side by side on my desk. After about an hour, the temp and humidity agreed. I bought these to put in a golf cart. I will update this review when I have used them for a while.
