I was surprised by their very small size, it suits me personally it easily slips into a pocket. Reception is good, and the practical temperature indicator. baterie the loads quickly and lasts long. The buttons are hard for us not suffisement may press it by accident and suddenly to deregulate the device. Very good products. I just note doubt on the reliability of the seller (Made in baby) because the package "amazon" ok but the product packaging was far from clear! I'm sure he was already open!
