First, in my 68 years, I've purchased a LOT of tools. BUT, this 45 piece set of Truly "Precision" drivers exceeds ANYTHING I have ever owned before. I was expecting a so-so set of drivers from China, but what I actually got was a Truly EXCEPTIONAL set of drivers... starting with the case. The case, is well built, spring-loaded "Top", and when you open it, ALL the drivers kinda "Swing-up" into view, so that you can really locate exactly what your looking for. This was REALLY well thought out! The "Quality" of the "Pieces" also seem to be of exceptional quality and the "Magnetics" of the Handle ensure that each and ever bit, you will Ever need is STRONG. Also includes an "Extension" and set of "Tweezers"... the only thing I added was a "Guitar Pick" to help in "Separating" Plastic parts of a computer, phone or circuit board.

Hopefully, they are as Durable as they appear... don't know because I just received it today, but I'm hopeful and looking forward to many years... or what I have left, of the Best set of drivers I have EVER owned... and trust me, as a Retired Law Enforcement Officer, I'm sometime Very Hard To Please. They are worth the money, and you won't be disappointed!

Everything you need in a convenient package. I have a set that I keep with my 3D printer and a set for the workshop. I liked the set so much I gave one to my father-in-law for Xmas for work on his RC cars.

I purchased this kit in order to switch around the clip on my Kershaw knife which required a T6 bit and because of the value of having so many other tiny bits for misc items like eyeglasses and computers. The job was done in less than a minute! Nifty carrying case with springloaded lid that even lifts the rows of bits into standing positions as you lift the lid! And the end of the handle stayed stationary as the grip and bit turned, that was very nice so I could hold the knife still has I turned the driver!

I work as a Communications and Security Technician and I am constantly using bit sets like this. I have owned several over the years and this has been the best one. One of the things I like most is the case. It closes securely and opens easily. As it opens the little bit trays turn up giving you easy access to the bits. I've used some of the tinier bits and they have not broken. Which is more than I can say for some of the other sets I've used over the years.

If you are looking at other sets here are a couple warnings...

I had a set that was had a long metal sleeve that the bit set slid in to. The bits attached magnetically on each side and then the whole thing slid and locked (sometimes) into a sleeve. Those are junk. It's a pain to get the bits off and the locking mechanism kept getting jammed so it wouldn't hold. It looks like there is one manufacturer of these and then it's branded under 20 different companies on Amazon. Avoid these.

I had another set where each bit slid into a rubber holder. There were about 6-8 bits per rubber piece and then each piece sat in a tray. This was trash too. The lid didn't close right, the rubber holders and everything were constantly falling out, and I ended up throwing it away.

The long and short is that you should get this set. I've gone through the headaches of buying other ones and I have finally found a good one.

Recently used this for the first time when doing some PC work and made the job much, much easier. Has just about everything you needs in a very compact, well built case. Also, the magnetic head is very strong, even with the extender - very helpful. After having used it on just one project, I would not want to work without it.
