It's good and excellent at its price range ad works correctly. But the thing confusing in this is that the pins markings I got confused which pin is shutdown and which pin is gpio... It's just written x and e . Soo it's kinda confusing but it a good product from what I have tested
It's works perfectly and I good overall in my opinion
