VIVID vision Unisex Adult Nylon Eyeglass Holder Strap Cord | New Chain Adjust on Sunglasses | Anti-slip Retainer Lanyard String Eyewear Frame | Specs Mask Chains

Good one

The item is rugged and strong but not so attractive to catch the sight of others.

It is very easy to attach to the glasses and very comfortable on the neck when the glasses are hanging

The threads are thicker than it appears. That’s it.

Easy to use, fits all specs and doesn’t look odd or old. Anyone looking for a simple solution to ensure they carry their specs along should consider this. Once you put the strings on, rest assured, even if you don’t need the specs momentarily, let leave it hanging and they will be secured for anytime use.

I have been using this product for the past few days. I feel it is risky for the spectacles. Though I tightly fit the product to the temple position of the spectacles by fully pushing the spring towards the frame, it gradually begins to slip away from that position. I even tried stretching the elastic during spring adjustment. I checked the card that comes inside the packaging of the product, and it had no instructions else I could have checked if I need to do anything special, which doesn't seem to be the case anyway. The company hasn't designed it scientifically, they are probably one of those companies that believe in marketing rather than solid product design/engineering. I will be searching for an alternative.

Ordered for a pack of 2 but got only 1

A simple but very strong and comfortable to use.
