Premium-Quality Micro Precision Screwdriver Set - Eyeglasses, Sunglasses, Watches, Jewelry, Electronics, Repair Tool 3 in 1 Mini Stainless Steel Screwdriver Flat Head

This is a perfectly serviceable set of eye glasses screw drivers. The machining is precise enough to fit the screws in the various glasses I tested. I would be a little concerned carrying this on my key chain daily because I can see how easily the threads could loosen and fall off. They have installed small rubber grommets intended to keep the pieces tightly threaded against each other, but over time it's inevitable they would loosen. I carry mine in a small pouch, so problem solved. I think the price is a little high for what it is, but it's not a relatively high cost.

I bought this screwdriver to tighten my glasses: they are advertised as micro precision. However, they are too large! So I actually couldn't really use them for my glasses. If that's the use you are looking for, do not get this. Most glasses come with universally sized screws, and trust me, these will not work.I am giving them 2 stars because they keychain is kinda adorable. It's just a cute knick-knack that is not useful.

This does what is advertised, a tiny screw driver with one flat and one phillips on the other end. It took weeks to arrive from overseas and I had forgotten I ordered it.

It was great while it lasted. Broke off in 2 pieces after 2 months and now no longer useful. Need something stronger and more reliable.

This is such a handy item to have. Even if you only wear sunglasses at some point those tiny screws will come loose and this does the job. Great price and swift shipping.

Great tool for watches or other items that contain the smallest screws.

We keep this in our diaper bag so we can have easy access to open our toddlers fan when we are out.

Perfect tool for changing things that require a tiny screw driver either flat head or phillips.
