I thought I was buying something I could operate like a regular jeweler's screwdriver, where the index finger presses down on the rotating cap and you manipulate the tool with the remaining fingers. I'm an adult male with normal-sized hands, and I can't use this that way. The distance between the cap and the knurled shaft is so long that I can barely hold it, and it feels awkward in my hands. Ideally, either it would be smaller altogether or the knurled part would continue closer to the…

Doesn't work with the hinge screw on my eyeglasses because the slotted bit is just too small. Too cheap to bother to return it but I doubt that I'll ever find a use for it.

First of all, no instructions whatsoever were included. Secondly, NONE of the screwdriver "bits” fit the main apparatus at all. I have worked with eyeglasses for years, and have NEVER seen anything as poorly designed as this! Finally, it states that the various screwdrivers can be stored at inside the main device by opening the cap at top. Cap just spins around — cannot be loosened or tightened. DO NOT PURCHASE!

If you're thinking of buying this, save yourself some time and just flush your money down the toilet.The product appears to use a simple compression fitting to hold the bits securely. Each bit has two small tangs on the side which should slide down into slots in the inner sleeve, then when the knurled compression nut is tightened, the inner sleeve should tighten and hold the bit. Unfortunately, there are no slots cut into the inner sleeve to accept the bit's tangs, which means that it is…

I am trying to fix my phone but none of the heads of the screwdriver fit to the little pins on the iphone. That's my feedback.

OK if you only need a few sizes in bits.For only eyeglasses I imagine its adequate.I found a much more complete set for a little more money.

This is an ingenious little gadget. I use it to tighten my reading glasses. With the other tool I was using I had to tighten every few days, but with this one, I haven't had to retighten yet. I've had it for a couple of months. Great buy. Thank you!

It does what it's supposed to do! Easy to use, portable, seamless. Just be careful so you don't accidentally injure yourself, or overscrew your glasses and crack the stems (can happen with cheaper plasticky frames).

I bought this for working on RC planes, servos and such. It works great and has all the heads I've needed so far for the tiny work.

This tool came in handy when I needed to replace the battery on my laptop. I love the size options and I can't wait to take something else apart.

I got this to change out my battery in my watch. Worked great for that. Then I realized that I could use it to tighten the screws in my glasses, too. Which again, works great for that. Then I realized that the two additional tiny Phillips/flathead tools will do both of those things as well, and they’re so little that I can keep one in a small purse and in my tiny office at work and now I can fix my glasses wherever I am. Love it! So cheap for three separate tools.

Small screw drivers are super hard to come by - however if you have a sunglass addiction AND wear reading glasses.ITS A MUST. This tool was super easy to use and i love how it gives me different head options. It's like buying a handful of tiny screw drivers for the price of one. And the seller was super awesome with follow up to make sure the product arrived okay! :)

The fittings on this little instrument are very satisfyingly fine-tuned. The grip is large and textured enough to handle in spite of my carpal tunnel, although I AM prone to losing the bits, which are so small i need my glasses to identify them. But this tool offers extreme precision and a very solid construction—bits have zero wobble or give when properly installed. And it tucks away all pointy bits to stay safely in a pocket until needed (there's room for all the bits in the handle).
