I used the 30/10 from Ray for 3 years without a single failure, but I did do all the connections and waterproofing my self. Last year I switched them all to the 12V 30/30 (the kind with the little buck converters every meter on the back) and the only "failures" I had are where I didn't do the the connection/waterproofing myself and relied on Ray's job there. That was the mistake. I have had several that failed due to his poor waterproofing. I took them apart afterword and discovered that on the incoming end where there it the 3 wire going in along with the extra 2 wire power, he injects silicone around the wires, but doesn't get enough/any between the two so water can get in between the wires. I've now cut them off and replaced with my own. When I inject silicone into the tube, I inject enough that the first one or two pixels end up completely covered in silicone. Probably overkill, but like I said, I haven't had an issue with the ends I've done.
