After three years of constant use my trusty old pen didn't work when I swung it open.
This pen has seen brewing, BBQ and cooking on almost a daily basis and has never failed me. Hell I even take my temp (orally) with it from time to time and recorded a 105.4 fever when I had the flu.
Thought it's time had come but a couple new 2032 batteries and the thing works like it arrived yesterday.
What's your experience with this pen, those that have one?
