Bought 4 and compared. Indeed the difference between Max the lowest and the highest in temperature does not exceed half a degree, when the humidity is, it seems even more precise. The thermometer has a notch to hang on the wall and a small paw pose standing on the table and a C or F button, the plastic is honest and quality is satisfactory buttons if you spend your life not to click on it. One regret is the battery (AAA) that is to buy more but considering the price ... Conclusion: good product cheap. Definitely recommended. Neat delivery.
