### ⭐⭐⭐⭐⭐ Great Product, Value
*by B***Y on October 21, 2025*

### ⭐⭐⭐⭐⭐ Good Quality
*by A***R on October 15, 2024*

The material is very good quality. The holes for the safety clips are drilled and have sharp metal that was not filed off after drilling. Other than that they work great.

### ⭐⭐⭐⭐ Gasket dimensions?
*by T***S on March 1, 2025*

Love the price but the fittings wouldn't push together close enough to twist into a locked position. I tried hard. I had to grind down the gaskets and then they connected well. Not a fan of rubber dust though.
