Drives my nuts like never before
I don’t like to bust a nut. But when I need a loose nut, this baby is just what the doctor ordered. Whether I’m using my left or right hand, this is the right tool for the job. It’s magnetic too, so if I have a screw loose or I want it to stick to my nuts, I can trust it to be there for me.

No better nutdriver
I bought a few of these the other day in a couple sizes and nothing beats them. I really didn't feel like shelling out major bucks to get the entire set, as there are a few sizes that I can't foresee myself using. I ended up purchasing the 5/16, the 1/4, and the 1/2, and couldn't be more pleased with them.There really isn't too much to say about these except that they are the best nut drivers I have ever owned, and I can foresee them lasting a very long time before needing to be replaced.

Worth it.
Happy with purchase. Used it to replace my refrigerator ice maker. The magnetic head and dedicated design saved me countless swear words I think trying to replace nuts upside down and at odd angles. Very glad I spend the money.

WAS A 5 NOW ITS A ONE!!!!!!
WELL LETS SEE I AM NOW MAD, THE NUT DRIVER THAT THEY SENT TO REPLACE THE PREVIOUS DEFECTIVE ONE IS ALSO DEFECTIVE OR THEY CANT READ. ITS SUPPOSE TO BE A MAGNETIC DRIVER WITH A HOLLOW SHAFT FOR LONG BOLTS IT IS NOT IN FACT THE END OF THE NUT DRIVER IS PLUGGED UP WITH THE MAGNET. SO I AM SENDING THIS ONE BACK ALSO WITH A VERY NASTY NOTE. KLEIN TOOLS USE TO BE THE BEST NOW I AM NOT SO SURE

Does the job.
You can be sure that it's not going to fail and perform well based on the name. The tool isn't anything special, but the peace of mind the name gives is worth something.
