Summary: works great for me
Comment: I had one of these for 2 years now and it performed flawlessly every time. Last month I gave mine to a relative and ordered another one. It showed up in great working order. Since the 2 previous reviews that I saw when I was reordering are all negative, I thought I would share my positive experience. The only reason I did not give it 5 stars is because I wish it use AAA battery instead of the button battery. Also, this one still requires a protective cover on the lense to work. I think some of the newer ones don't. But, considering the great price and how long the covers last (I didn't have to change the cover in 2 years and the box included 10 or 15) this is still a great deal.

Summary: Don't buy this product
Comment: Same as the other review. The thermometer will not turn on. I won't change the battery because I don't think I should have to pay for it if I bought a brand new product. I will return it and buy a better thermometer.

Summary: Does it work?
Comment: Would not turn on. Replaced 2032 battery with one of my own (the original battery was dead). It does work, after a fashion, but I'm not going to rely on it. "New" unit had two readings in its memory -- don't know if that was quality control or another person trying it out before Samsung repackaged it -- don't care either. Dead battery should not happen, and leaves me wondering just how long Amazon has had these.
