Very low quality. I'll end up throwing them away or using them in a pinch until I find better connectors. This is one of those cases where I haven't carefully checked the reviews. It's just not what I'm used to. Really cheap quality. Read the content of the image carefully to make sure it suits your needs. There are no AWG #12 quick disconnects. Update May 18, 2020: Added images showing the difference between a decent roundabout and this one. This item is on the right side of the two photos.
