TEKPREM 1/4" Strong Magnetic Extension Bit Holder, 5 Pack Hex Shank Screwdriver Bit Driver Set with Portable Case for Holding Screwdriver Bits and Screws

Very strong magnets worked as described

Work great , great quality

As a homeowner who likes to work with his hands, I use my drills almost every day, and I find a bit extension to be indispensable, not only to add length to the bit, but for quick bit changes. The TEKPREM 5-pack is an excellent value for the price. With five in the package, I inserted my most commonly used bits in several of them, making quick changes a breeze. I recommend highly.

Give s needed extension and holds bit adequately.

Happy. I lose these all the time and bought them after getting tired of looking for one of the 3 I already owned. Now I have 8 an cannot find one. HAHA

I would choose 1 star if 0 were available only because the case looked nice.I used this on my M12 impact for 1 day, while walking and nothing touching the bit I lost it multiple times. It seemed like it held well, but would just fall out quickly. It’s good if you plan on putting the bit in for second to use, and then take it out. For overall use, unfortunately it’s not even worth the price.

Somehow, these bit extensions seem to fall into whatever dimension also holds the infinite number of lost 10 mm sockets and laptop screws. This 10-pack of bit holders has neatly replaced all of the ones that were missing from various tool kits, and the extras I keep in the snazzy little plastic case they came in. (Yes, I said "snazzy." It's nice not having them rolling all over inside a tool box.)Very good quality. Would recommend to anyone who uses their tools with any regularity.

These bit holders are fine for regular drill but they are not impact ready. Magnetic part of the holder breaks after driving about 20 screws with impact driver.
