Pros: Easy to connect, does not have issues with lining up the center wire. After connected stays put.

Cons: None discovered yet

Other Thoughts: While Crimp on coneectors are most likely better, they are a one time shot if you don't get the wires lined up they are wasted. With Twist on you can take them off and reseat.

Pros: These work great and are easy to put on the RG59/U. They are very tight and hold well.

Cons: None

Pros: I have installed many of these now. If I have a video problem which is rare these are easy to unscrew and check for stray strands. Great item.

Cons: None

Pros: these work well and are pretty easy to install but they do take a little longer than crimps i think

Cons: None

Other Thoughts: I see some other people are having loose fits but mine are nice and tight on rg59u I would say you can hang at least 20 pounds off the finished termination

Pros: Works in a pinch, or if you don't have those pricey crimping tools. These are also easily disconnected and reused.

Cons: Somewhat difficult to work with. I used it with standard RG-59/U and had initial problems with stability. A little bit of electrical tape goes a long way!

Other Thoughts: The price is attractive, and if you don't plan on doing a lot of cameras - then this is perfect for you. I didn't notice any loss of video quality vs other crimped ends. However, for a truly perfect fit'n'finish, I would recommend going with the crimp.
