HAIKUSOUBI Torx Head Screwdriver Bit Set, 1/4 Inch Magnetic Hex Shank 3 Inch Long Drill Bits，12pcs Tamper Resistant Star Bits Set S2 Steel, T5 T6 T7 T8 T9 T10 T15 T20 T25 T27 T30 T40 (12 pieces)

These worked well but we’re a bit short on the shank. I was counter sinking finish screws for a jamb extension and needed 3” to reach the bottom of the hole. The shaft taper is only 2-1/2” long and didn’t quite reach. Had to buy longer screws and drill shallower pilot holes.

These things are great for working on small things that are not torqued too much. I tried to use the T30 on the rotor screw on my car when I was changing the rotors and the tip snapped off, I know those screws can be about impossible to remove BUT I used a regular T30 screw driver and I got it loose without too much trouble. I contacted the seller and they send out a replacement, no questions asked.These are nice and I recommend them, just don't use them on high torque stuff :)

I am very happy with these security tools. They are long easy to use with hard to get deep screws.

I needed the length especially for the smaller size hard to reach places they do that

was given as a gift. Works great repairing different items.

These work great. I needed a longer bit to mount an optic and this product worked perfectly. They are strong enough to use a torque screwdriver with. They engage the fastener great.

These work fine nothing wrong with them.

Shame on me but I should have read ALL the reviews. It specifically says magnetic but they are NOT. I failed to check every word in the description as a few other reviews also state NOT MAGNETIC. Probably will not return.UPDATE: Decided to not return as this was only product I could find that had a storage/display case which was the discriminator when I bought them. I did resolve the issue myself when I recalled an old physics experiment. Pull the wrench bit end lengthwise over a strong permanent magnet about 6 times and it will arrange the domains in the steel and magnetize it; works. If needed in future, you can do it over and over to increase the magnetic field. I've used this on screwdrivers also.
