I must confess that I only bought this screwdriver because it seemed like the cheapest way to get a small DC motor with a good high reduction gearbox below 10mm in diameter I needed for a project in making. But after I received the screwdriver and using it for a bit I decided it would be heresy to use such a good piece of engineering for that purpose, and I dismantled my previous, much more expensive, screwdriver instead, and use this one as my new primary small screwdriver.If it was just the screwdriver it would already be a great deal, since it is well made, robust, high quality and very ergonomic, has a great feeling and includes a LED light that's actually useful (and illuminates 360 degrees, a great touch). That alone would be worth more than the $20 I paid for it.But in top of that, the kit also includes a magnetizer-demagnetizer tool, an an extremely complete set of tips, including lots of very useful security tips that aren't often at hand when you need them. So if you are looking at this screwdriver, stop looking, this is the one you want.Edit: after using this screwdriver quite regularly for a few weeks, I had one small issue, which could be a large one if the screwdriver is abused a bit. I was trying to remove a stuck screw, so I helped the motor by turning the screwdriver manually, and that caused the casing to rotate relative to the motors and tip, and the rubber buttons popping out of place. I was able to manually rotate the casing back into position and press the buttons back in place easily, but I can imagine this could have ended badly if I hadn't stopped immediately. So my recommendation is not to use this screwdriver for the initial turn of stuck screws, use a manual screwdriver for that situation (I keep a manual handle that's compatible with the included set of 1/8 inch bits for that), and use this tool to finish the job once the screw is moving. But it would be great if the product was improved with a bit of glue between the case and the mechanism to avoid excess force causing this problem, since the parts themselves seem to be sturdy enough for the hard jobs. Still an impressive product though, super happy with it.
