Drill Bit Extension Set,4Pcs Magnetic Drill Screwdriver Bit Holder Bar Chuck Adapter Extender 1/4 inch Hex Quick Release Bit Holder for Impact Driver

made getting into deep space so much easier.

They work as intended they feel a little flimsy and I can't see them lasting

I purchased this set of 4 drivers which come with 2", 4", 6", and 12" length. The first time I used the 12" driver, the end started to spin on the driver shaft and would not drive the screw. The ends appear to be crimped on, and the crimp was slipping and would not produce enough torque. The others work just fine, and I am happy with them, but when I contacted the seller and told them that I received a defective product, the response I received was:"Dear friend, thank you very much for your support of the store. But I'm really sorry. This product cannot provide separate replacement packages. I hope for your understanding."That's all. No offer for replacement or refund or anything else. So I paid for 4 drivers, and received 3 that work. Beware.Update: The seller has offered to refund $4. The cheapest replacement I can find will cost me $11.Update: After a small amount of use, the short driver is broken - the latch mechanism no longer holds the bit in place. I recommend staying away from this product and seller. Spend a little more and get somthing that works.

The bits wobble once inserted in the impact drill socket, and it hold bits loosely. Beyond confort and usefulness. Not that much of an issu if used wit a drill and short bits.Would return the thing if I can.

I bought this 4-piece extension set together with a magnetic driver handle and collection of magnetic tips to handle any situation. If you've ever tried to find a long screwdriver (like 24") and then didn't even know if it was the RIGHT TIP or not, you can see why building your own long screwdriver is the BEST OPTION.These extensions have sliding-gripper connectors. They don't come loose, but where a long connection plugs in to the driver handle might, so this is where the insurance of a short piece of duct-tape keeps it all together. With the tip, extensions, and handle I can have more than a 30" reach, which is longer than I need. But who knows? Most screw-driving applications won't need an extension at all. But then suddenly, there's THE ONLY WAY you can do it: get a really long tool and a head-light!
