Review: Good quality - Good quality and all worked upon arrival. Very nice for prototyping and soldering to boards.
Review: For ender 3 pro - Bought these for the ender 3 pro. Even though I just needed the 2 terminal block, this was too good of a deal to pass up. The power con was fried from the factory due to arcing and these worked perfectly. I de-soldered the old and in with the new. Been perfect since.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good quality
*by A***I on June 10, 2025*

Good quality and all worked upon arrival. Very nice for prototyping and soldering to boards.

### ⭐⭐⭐⭐⭐ For ender 3 pro
*by D***G on May 1, 2021*

Bought these for the ender 3 pro. Even though I just needed the 2 terminal block, this was too good of a deal to pass up. The power con was fried from the factory due to arcing and these worked perfectly. I de-soldered the old and in with the new. Been perfect since.

### ⭐⭐⭐⭐ Read the item name carefully...
*by B***K on October 23, 2021*

...don't rely on the item picture. The picture shows 25 2 pin terminal blocks. The item name, or title, says "20pcs 2 pin". What you get is 20 pcs of the 2 pin terminal block, not 25. Also, like someone else mentioned, the pins are a bit thick. Not a problem if I were designing my own pcbs, I could just design the pad/hole with the proper dimensions to fit the pins. But if you're using a pad-per-hole boards, you might run into a problem. The pins wouldn't go through the holes of the pad-per-hole boards that I tried them in. I had to file the pins down a bit to get them to go in. Still, for the price, it's not too bad.
