Yakamoz Pack of 3 Pieces 1/4 Inch Hex Shank Magnetic Extension Chuck Adapter Quick Release Bar Socket Screwdriver Bit Holder

These are very useful while working and seem to last well. I generally misplace them or unintentionally donate them to others before they ever wear out, and I don't remember having ever broken one yet..I generally keep two or three with each of my cordless drills just so they are convenient to get to.

Works for my intended use. Made my own tool handle and just started using it. We'll see how it holds up. I may update this review if it doesn’t last long. First impression is the magnet could be a bit stronger.

I like the fact that they were well constructed and they hold the bit tight i’ve changed my mind about this too. It’s crooked. It holds the bits and stuff, but it’s it’s bent or something. In fact, all three of them are. I don’t think I’d recommend this to anybody.

On 2 of the 3 the black cuff is just loose and slides back and forth. The bit is still held in until the cuff is pulled all the way back, but it's just poor qualityOn all of them when you apply pressure to the bit it pushes the bit another 1/8" so the bottom of the tool head itself is just inside of the cuff. It's still functional for my normal usage, that's not typical how these holders work.Overall you get what you paid for. They aren't great and I don't expect them to last long with a lot of bit swaps or even moderate use, but they are cheap enough to have as extras just in case.

These extensions work good, I’ve been using them for 4 years. Have not had one fail.

Bought a set of three adapters and every one is not concentric. The hex that goes into the drill is not in alignment with the chuck that holds the bits. It's obvious, the bit chuck was pressed on the the hex and is not in alignment, so every bit you put in the adapter, wallows around. Just cheap crap, that's all they are.

I love it. All three adapters work fine. It is a great deal. I've been looking for a small adapter like this in big box stores, but all they sell is an expensive kits.

This is a great adapter when you need to change up bits pretty often. Locks and releases bits with no issue.
