    Awesome product
  

*by N***H on Reviewed in India 🇮🇳 on 9 April 2019*

I wanted just a device to display room temperature on my 12v diy cooler & checked other products of 500+(with probe) and those were normal black n white display. But this chipset has glowing display + metal probe, also accuracy is on mark. Very sarisfied with the product & recommend it if you want to use on a 12v project, else use any 12v adaptor.
