Pros: I've had no issues with these whatsoever. I've used them in a few computer builds, and in pretty much any other situation where they'd come in handy. They're good and tough and long enough that if they can't do what you want them to, you should probably use something other than a zip tie.

Cons: None.

Pros: Not expensive

Cons: Very brittle and easy to break. Easy to snap in half and lock tab would frequently break off during installation.

Pros: They are black?

Cons: These things crack apart in my hands. Maybe I just got a bad batch, but they are useless. If I am not extremely gentle the tab breaks out of the clip when I zip them. And I can snap them apart with my fingers alone.
