These work great! We've used other brands in the past and they don't hold up.

These appear fantastic with the polyelectric tape, However, they are not made from a UV resistant plastic and within 1-2 years the plastic becomes brittle, breaks and crumbles. This causes a continuous need for maintenance to purchase new replacements and time spent replacing the broken pieces to maintain the electric polytape. The company needs to use a better quality plastic. I guess that would mean that they would loose money by making a better product as they woud not sell as many replacement parts. So, I either keep buying these parts, or need to give up the poly tape and continuous replacement parts, in order to replace with a different product altogether.
