## Customer Reviews

### ⭐⭐⭐⭐⭐ Flowmeter does what it is supposed to do.
*by S***N on September 25, 2016*

Good flowmeter for the price. It does operate the way it should, is lightweight and easy to install. I use it it in my portable rig and it seems durable enough.

### ⭐⭐⭐⭐⭐ Great valve for the price...
*by J***N on January 5, 2018*

Installed this regulator on my tig welder... First impressions is that is seems like a good quality valve. It screwed on to my existing hose fitting without trouble. Adjusted gas flow perfectly and is still working. I am impressed so far and would buy again.

### ⭐⭐⭐⭐⭐ Good regulator
*by A***N on June 23, 2015*

I like how nice the needle valve feels. You don't need to tighten it hard at all for it to cut flow of gas. Seems like a quality regulator. I use it with my TIG welding setup.
