### ⭐⭐⭐⭐⭐ It works!
*by S***3 on March 25, 2022*

Wow! I had heard about Ridgid tools for a long time; this was my first experience with a Ridgid pipe wrench - why did I wait so long?? The aluminum is so much lighter than the steel, yet it still is strongly made. No one has to be concerned that the wrench won't be strong enough to do the job. Quality is exceptional - there are no clunky or stuck parts in any of the pieces. Worth every penny to have this wrench for use. Thank you, Ridgid, for making such an excellent wrench!
