    Sturdy tool
  

*by C***3 on Reviewed in the United States on November 9, 2023*

Sturdy tool made of durable material. Worked great for intended use.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Works fine.  Need to file off burrs before using.
  

*by J***P on Reviewed in the United States on June 21, 2023*

These work fine.  However,  all three of them have burrs on the ends that need to be removed before use, lest you nick the seal you are installing.  It appears that the ends are cut with a shear and not de-burred afterwards by the manufacturer.Would be five stars if they did not have burrs on them.
