This is a very poor quality thermometer. The cord is very short and doesn't stretch nearly 4 feet and you have to press on the connector where it connects to the device. The question is whether the temperature reading on the device is the actual temperature or just another poor reading due to poor build standards. I will never buy anything from this company again simply because they knowingly sell very poor quality products. The $50 I paid for the product was worth the knowledge I gained about this substandard product and its seller.
