Rated 4.5 out of 5 by 24 reviewers.
Rated 4.0 out of 5.0 by neat little set of tools. I don't often need most of the bits in the kit but they are good to have if I do need them. I occasionally run into a tamperproof screw when repairing battery packs and this set will provide the needed bits if I do encounter them. June 9, 2015
Rated 5.0 out of 5.0 by good selection I am a professional carpenter, and you never know when you may need one of these bits. This is a must have item or you don't look like a professional who is prepared for the job. February 13, 2013
Rated 5.0 out of 5.0 by Good product, and assortment of bits exactly what I needed, good quality of bits at a reasonable price March 25, 2015
Rated 5.0 out of 5.0 by Nice set This is a quality set of security bits. I researched others, that were less expensive, however it could be easily seen that the quality of them was substandard. In particular, the pin holes are not centered, like that in the hex and torx. The Klein set bit holder is made of rubber, which makes it easy to remove and replace the bits with one hand.

Rated 4.0 out of 5.0 by Great Assortment, Not so good quality First bit I used out of the set snapped off in the bolt. Others that I have used seem to be made of a softer kind of metal as they've tended to twist or round off. I suppose these are so specialized that the metal they're made from is unique. Since I have to use these, I'll have to keep buying the set to replace the ones I keep damaging. June 3, 2014
Rated 5.0 out of 5.0 by Exactly what I needed I needed a special bit in order to replace the lightbulb in my microwave. This kit included the correct bit along with many other tamper resistant bits that I can use for other projects. This was exactly what I needed. December 31, 2013
Rated 1.0 out of 5.0 by Not what I expected in durability The T-8 bit rounded off after the first few uses. I would not recommend paying a premium price for these bits. May 7, 2013
Rated 4.0 out of 5.0 by Tough Find You will be hard pressed to find a collection of tamperproof bits or drivers like this anywhere else, even online. They are bits only, not compatible with the average modifiable driver so you better have a drill with 4 to 8 torque. No more or you could damage the screw. If you run into this stuff a lot, especially with electronics and appliances. Get this set now and you won't have to worry for quite awhile as it includes all the current and older style tamperproofs. August 2, 2014
