Chatting with Chris Young on Reddit on the subred for his new Combustion thermometer, and he mentioned something about designing the Joule that I've never heard, and I've owned 2 since 2017:
The space between the body and the foot of the Joule is a clip to hold the end of the power cord.
I just ran over to the kitchen, and it's true!
Just blows my mind that I didn't realize that and I've been wrapping and knoting the thing for all these years (they never told us, did they?)!
