Works great

### ⭐⭐⭐⭐⭐ Good value for the money
*by A***R on 16 May 2026*

I bought this for my hubby. He has found it to be very useful and the durability is top notch. It was a good value, easy to use.

### ⭐⭐⭐⭐ It does the job and seems to hold pressure when turned off.
*by A***N on 26 June 2026*

This unit is very simple and easy to use - just dial which function you want and use it. If you want more fine adjustments on the flow rate during brazing, look elsewhere, but for simple basic function, both the purge and the braze function do their thing. For small jobs, the braze setting might flow too much, and this item is not adjustable.
