Just opened the package and tested, seems to be fine. None of us have fever but checked it out on the option for "surface temperature". Seems accurate on body temperature too. As someone wrote in the comments, the battery placement was weird, and i've never see + side being placed on the spring. Almost thought the piece is faulty, but then thought of other possible positions and finally decoded the hidden message in the symbol. Weird :). Overally seems a good buy for the price, especially in the given scenario.
The product is good but should not have been sold "with pride made in india". The function of switches is reverse. The button switches have different function than that what is mentioned. Better write "Made with pride in ....". However, the product is cheap and useful. The acvuracy is acceptable cost is low. I recommend.
