Only 6 out of 10 working properly. I gave 2 stars because )east is more than half the work, so it's something, isn't it? Yes, we connected them correctly. No, we didn't unscrew the screws or try to wrap the wire around them. It's not 1985 and we're trending. It's been a few days since my return window but I don't even know how that would work. Do I return 4 scraps or do I have to return all 10 for a refund. Ah, what a nightmare. I think I'll take what I can get.
