4xAA Square Battery Holder with Cover

With one exception. The solder on the red wire seems to be always lacking and the red wire would just rip out. I had to resolver them. Other than that they work well.

The cables easily come out if they get pulled a bit, I expected them to be more resistant. The on-off button is useful, but it is on the bottom side of the battery holder, making it harder to use in some situations. It's not terrible, but there are probably better choices.

Awesome battery holder for servo driven robotic project. The switch saves so much trouble.

Is working fine. The on and off button is handy.

It works well. The built-in switch saves having to wire in a separate switch, and the cover makes for a clean look for my project.
