I like mine but it does make more noise than my Bluetooth one.
You also need a higher water level for the nano and can only attach to slimmer pots (not coolers etc)...
The thread on the clamp is much better and requires less turns to tighten Vs the original.
The unit looks much smarter than the original, and actually makes the original look dated in my opinion.
I only use the BT version when I’m cooking two things at the same time at different temperatures.
Heard a few moan about the lack of a temperature wheel but it’s not bothered me tbh...
