### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Sturdy!
  

*by B***N on Reviewed in the United States on October 28, 2020*

This thing is built really well.  I've had it installed for a little while now and have tried others.  This one is built to last.  Its 2x more expensive than the cheaper butterfly valves but the quality is there.
