I read all the reviews and decided upon this thermometer. Big mistake. I have arthritis in my hands that isn't yet severe, but makes gripping a bit difficult. I had to struggle to get the sheeth off. There wasn't enough unsheathed thermometer to give me space for a good grip. It worked OK as far as temp was concerned, but it was difficult to shut off. You have to push in on the end of the thermomether, and it kept turning off and on again. After months of wellness, and therefore no need of a thermometer, I took it out this morning to use, and it would not turn on. I struggled to get the cover off to check the battery and can find no way to change it. The thing no longer turns on, so I went back to one of the old mercury ones left from my childhood. Very disappointed. Save your money. I think the designer was more interested in making it look like a cool sort of space probe than on whether it was actually usable. Must have been a Treky.
