Which Bottle Keeps Water Hot the Longest? (33 Tested!)

Our biggest, most accurate insulation test yet! I did hot water insulation tests on over 30 bottles using wireless thermometers to measure the exact times that the bottles changed temperatures. This video reviews the results, the top five conclusions, and the testing procedures.

I'm testing a "reverse video format" with this video by putting the results and conclusions first, then looking at the testing process. Hopefully this gives you the usable info you're here for first and saves you some time. Please let me know what you think so I can figure out if you all like this format, and if the video does well, I'll use it again in the future.

Paid Promotion: Technically this video is marked as "Paid Promotion" because I received some bottles for free. This did not affect the results or testing in any way, and I did not promise the brands anything in return. I occasionally accept new, interesting bottles because as a small Youtuber, I can't afford buying all the new ones that come out, and I hope some of you guys are interested to learn about them.
