Aylifu Eyeglasses Chain Connector, 40 Pieces Adjustable Eyeglasses Chain Ends Rubber Strap Holder Chain Loops for Eyeglass Sunglasses Chain, 4 Colors

No complaints and it works and fits well.The ball slides which makes it adjustable to the side of the glasses temple.

So glad I bought these. I am always snapping these off the chain. I also make sure that any chain I purchase lets you replace them.

I have made a few Eyeglasses chains with these and they work pretty well. They only negative is that the rubber stretches out and you have to keep tightening your ear pieces on or your glasses will fall off. It needs a more durable rubber or a way to tighten it so that it stays in place. I do like how easy they are to work with when I am making my eyeglass chains. For the price and quantity, I would recommend.

I thought I'd never find any glasses loops/connectors that I could use with confidence. All the others I tried never failed to fail. I never knew when one would slip off and my glasses would fall off. So I was skeptical when I ordered these. But lo and behold after 3 months I'm still using the first pair. Yeah, every once in a while I give the rubber a tug to tighten things up...but not often. I can't tell you how frustrated I'd been until I bought these. They work for me even though the arms on my glasses are pretty thin. I can't guarantee they'll work for you, but if we're a betting man I'd bet they will.

Good for the money

It's a real challenge finding glasses connectors that actually work. They' have only one thing to do (hold glasses), and most of them don't. The two secrets in these is that the ring is made of rubber, not silicone, and the coil in the center is longer. Silicone rings stretch too much and don't hold. Small coils in the center allow for too much slack, and glasses fall off. These are the right composition, a good design, and they really work.

Can't beat the value but lacks a little in functionality. The beads don't stay tight against the rubber loop so the ear piece slides down and I have to pull the loop back up and tighten the bead. I wear my reading glasses around my neck all the time so maybe they wouldn't loosen up with less use. At any rate, the price is good and I'd be lost without them.

To get continued use of the chains that I like since I can now replace the connectors.
