### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    A lot less costly
  

*by R***. on Reviewed in the United States on August 23, 2018*

These plugs are typically $50. Paid $15 for this brand. Only down side is that the screws may strip out easier when over torqued. Upside beside price is the strain relief can be set to 3/8" diameter cord. This is much smaller than is usually accommodated.
