how does that work? Water flow, spin a rotor and generate the batt to light up the display and sense the temp ?

yes

 

when I turn on the water, the display turns on almost immediately, same when I turn off the tap

 

no noticeable drop in water pressure, the micro generator is well designed

I just tested it

 

two interesting findings about shower water temperature

 

1.from too hot to just nice to too cold is only within 2 degree celcius of difference

 

2.I always felt water getting colder towards the end and crank up the mixer to compensate, thought it was because of the small capacity of my water heater. Actually it is not, the water temperature didn't change, it is the body got use to the warm water and didn't feel it as hot anymore

Interesting. If only they have Bluetooth, then can hold your shower head like a telephone and pick up a call.
