Kestrel Drop D2 Wireless Temperature Humidity Data Logger, Orange

I used this on a recent backpacking trip. I had it set to log temps every 10 minutes for the entire weeklong trip. It worked great. Afterwards I was able to download the logged data send use it to graph the temps for the trip. It’s a great way to see what the temps were throughout the course of the trip - especially late at night when it got below freezing.

I went through 2 brand new batteries in a week's time, so it socks the power iut of it (even though I changed the settings so that it wasn't reporting data as often). It is also very slow to report info, even though it is near a window AND a router. I basically had to go stand in the coop and hold my Galaxy S10 phone right next to it to get them to connect. Massively disappointed
