2nd purchase. Used for Camping. One flaw.
My second purchase. This one is the newer version (post 2023) that uses the CR2032 battery which is much more commonly found in stores. The indent used to open the the battery compartment is still poorly shaped. It's radius is too large and slot too wide making it challenging to open/close it using a coincell battery; a quarter fits even poorer. A design flaw in my opinion. Otherwise happy with it.

Perfect for camping
I love having this thermometer with me when camping and/or outside swimming or fishing. It is nice to know just how cold it really is!

I really like this useful little gadget/tool! Works as you say it should. The button does take a little getting used to but once learned its second nature. Can't wait to use it camping this fall. Thank you!
