### ⭐⭐⭐⭐⭐ WORKS AND BUILT SOLID
*by D***O on January 3, 2026*

Good , solid, product ..works as expected

### ⭐⭐⭐⭐⭐ Works
*by R***. on July 6, 2025*

Seems to be holding up. Stopped the hammering I was getting

### ⭐ Not working at all
*by M***. on August 11, 2025*

It appears to not work. I purchased this as a replacement for an arrestor that failed after two years. What I noticed on this one was there's a non-metallic object in the bottom above the fitting where the piston would be. I don't know if this is the "ball" other purchasers mention being stuck. In any event the pipes are still getting rattled.
