## Customer Reviews

### ⭐⭐⭐⭐⭐ This product actually saved a pc build that I made.
*by N***I on May 14, 2025*

Saved my pc and they gave alot of them so its worth to buy.

### ⭐⭐⭐⭐⭐ Unique packaging
*by W***Y on January 11, 2023*

Came with a random wall plate and another bag full of smaller sized jumpers. Only about 20 of the ones I ordered but with the free “gifts” and only needing one I’m content.

### ⭐⭐⭐⭐⭐ Perfect jumpers.
*by N***R on March 14, 2022*

These are fairly basic little components, but essential when you need one. The jumper installs with some resistance, as it should. Recommended.
