Not giving any output after using just for a couple of days and I am out of returns period so stuck with a defective part which failed to perform its job. Can't blame the seller though. Its electronics and it can fail at any point of time.

    Worthy product for your DIY projects
  

*by V***R on Reviewed in India on 27 May 2021*

Package-GoodProduct quality-GoodPerformance-GoodMet my expectations and working well. The reason for 4 stars is the price. Else I would've given 5 stars. The very mild deviation is there when measured with a multimeter. But this is expected.
