Bad news. I've ranted and raved about these battery terminals, but Sky High Car Audio does not stand behind their products when they fail. Instead, they blame you the buyer. Really sucks too, I've really liked these things so far. I've had no issues with them up until these weekend. I had to weld on my tire carrier and I disconnected the battery as I always do and the set screw came out a little and just seized. It wouldn't come out anymore. Luckily it was enough to get the terminal off of the post. So I didn't think anything of it and just did my welding. Well, when I went to tighten it back up, it wouldn't move either. Nothing, just seized. I normally just use a small allen wrench because it turns very easily by hand. Being that it wasn't turning by hand, I got a small allen bit and put a quarter-inch ratchet on it. I snapped 3 tool bits and the set screw still didn't move. The 3rd one is still stuck inside the allen bore of the set screw and now the terminal won't tighten. And just so everyone knows, this set screw is tiny and just turns in and out. It doesn't need to be removed nor has it ever been removed. I tried pb blaster, anti-seize, etc and nothing loosened it. I put the terminal back on the battery post and it has made connection so I can start the Jeep temporarily.
I contacted Sky High Car Audio, and all they've done so far is accused me of cross-threading it even though the set screw has never even been removed from the terminal. I even offered to send them the old part or send pictures or anything so they could find out what happened. All they told me is that I probably cross-threaded it and it can't be warrantied. So anyone who has purchased these based on my recommendation here on the forum, I'm sorry, but they didn't work out for me. And I hope none of you have a failure with these nor have to contact the company because they'll just likely blame you for their problem.
Here's some pictures of what's going on. Here's the positive one, this is what it should look like and this one is not seized:

And here's the negative one that is seized and won't move at all. As you can see, there is part of a tool bit still broken in there:

I realize it's only 50 bucks, but it's more of the aggravation of dealing with a shady company that is the reason I posted. I wouldn't want to see any of you go through this.
