I have also never heard of this before, but these look really interesting! The battery usage is fine in its own right, but my scale always seems to run out of power at the worst moment. I usually cook without measuring, so when I take it out it’s because its services are needed, and I guess the battery tends to slowly drain in the cupboard.
I’ll keep this in mind for if/when my scale breaks - or if I need a Christmas gift idea some year! :)
Ideally while remaining more respectful of pussies perhaps, but that’s a stylistic choice.
