The little springs that tighten them kept loosening so they would make the glasses fall off.Loved the different colors of the lanyards but after 2 weeks the elastic that attaches to the lanyard lost its' 'elasticity' (no matter how often I tightened the elastic) causing my glasses to fall on the floor, my lap, etc. If there was a foolproof way to secure them to the temple (arm) of the glasses I would give 5+ stars.I love the fun colors and patters of the eyeglass holders. They are much more comfortable than the beaded ones. Not as bulky to wrap and put in a case. The only downside is the rubber holders are too big to grasp the piece. No problem I just loop it through both, it really tightens it up.This eyeglass holder is far and away the prettiest I have had. Since having cataract surgery, my glasses are really essential for reading, so I try to keep my glasses close at hand at all times. The soft colors of the shell beads work with whatever colors I am wearing. The colors are elegant and subtle rainbows. The holder is sturdy and very nicely priced. I highly recommend this! As I need it so much I am so happy to find such a pretty holder.I bought these to attach to a mask. I'm always going into a store and then realizing that I've left my mask in the car. This takes care of that problem, I put them around my neck before I leave the house and all is good! They are well made and very colorful. Love them!!Love the color and durability! Great purchase.I got these for my safety glasses and it’s the best thing I’ve done! I work in a hospital and when I need them they’re right on my neck!Like the chain and the serviceI have had these for a while now, months in fact. Love the colours, and they're practical. My only beef is that the rubber loops that attach to the arm ends of the glasses need to be tighter so they stay on better. Fix that and they'd be perfect.the holders don't hold the eye glasses well. My glasses fell off many times. Bad PurchaseExactly what I wanted. For me the chain is the perfect length and it seems to be very sturdy.I love it. It’s very cute and very useful for masks.I bought one a few months ago that recently broke and just bought two more that broke the first day using.
