## Customer Reviews

### ⭐⭐⭐⭐⭐ Exact Replacement for Miller Part.
*by J***E on January 7, 2016*

Great Product, Saved me a trip 30 Mile trip to the welding supply, and a handful of money. I bought 2 (2 packs) to have a few extras, this even with shipping a total of 4 of these tips, was cheaper than 1 at the welding supply (and it woudn't have been an OEM Miller either). My number was barely readable on the old one from so much use, but a couple of guesses on the last digit got me to this. It was a perfect fit on my Millermatic 250, which is an older machine, but I wouldn't trade it for a new one. I will be buying more from WeldingCity . They just won me over as a dedicated customer.

### ⭐⭐⭐⭐⭐ Good value
*by G***I on January 1, 2021*

### ⭐⭐⭐⭐ Four Stars
*by G***R on February 15, 2015*
