Excellent power balun at a fair price. I have used dozens now, with very few breakages or manufacturer defects. I torque mine tightly. Good for either Cat5 or siamese cable power wires. Even speaker or primary power wire of 18-guage or smaller should work well. I will be ordering more as needed.

For after market repairs, my DVR installer used twisted cables and electrical tape, making repairs clumsy and not very professional, this power connectors made easy to replace the power supplies when they fail and make it easy to troubleshoot they are of good quality and after installation if you cover it with electrical tape then they work perfect and look professional.

Product works as advertised. I would given it an easy 5 stars. T 3 stars reflect a very needy seller who begs for a favorable review with too many e mails.

Great product. Ordered these for my electronics projects. Received them and 4 pieces were missing screws. Contacted seller and they replaced the ones missing screws very quick. Would recommend these.

Perfect and easy way to wire LED systems

works fine

3 of the male connectors would not tighten and are no good. Wrote to Seller, but never got any reply after two weeks gone by.

The connectors work ok, but fall off easily. They don't really bite into the wire, it's more of a pressure fit. We tried to use them on a FRC robot and they just didn't hold up. If you're using them for a static indoor project they will probably work.
