I finally had to use these extensions. Right out of the bag, 2 have broken chucks, they do not lock the bit in. And they don't spring back closed. These are garbage and a complete waste of money. I feel stupid for not testing them when I received them. Folks, don't make the mistake I did buy these.

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.

These have been an amazing tool for automotive work. I use them in my m12 fuel hex drive stubby impact with a hex to 1/4” socket adapter. The only failures I’ve had have been due to asking too much from those little shanks. Commonly breaking where they lock into your tool when applying excessive force. Perfect for those smaller fasteners up to 14mm at most, anything seized can break these. I’d recommend breaking your fasteners loose with traditional ratchet and socket or a wrench, then use these on electric tool for setting fasteners and such. I first purchased this set about 2-3 years ago, again only failure has been due to excess force applied to the longest extension when I should gave gone w my 3/8” ratchet/extension/sockets on a seized fastener. Just ordered second set, this time the long extension bag shows signs of corrosion, but the tool itself does not seem corroded anywhere. Will update if anything odd is found. An essential for my tool box.

This extension set is exactly what I was looking for. I needed an extension to help with a small project I was doing. I only needed one extension, but this set's price was so reasonable that I bought it. The four stars was only because one of the extensions came apart. The spring loaded locking mechanism is pressed together. I simply had to re-press it and hopefully it will stay together. Good value.

I recently purchased the Drill Bit Extension Set (4Pcs Magnetic Drill Screwdriver Bit Holder Bar Chuck Adapter Extender 1/4 in), and it has quickly become an indispensable part of my toolbox.

Made from durable materials, they feel sturdy and well-constructed, ensuring they can withstand regular use without showing signs of wear. The magnetic feature is a game-changer, securely holding the drill bits in place, which saves time and frustration when switching between different bits.

One broke on the first use, the other broke after only a few uses. Poor, useless quality. Do not buy.

Really like this item they are easy to use, bits come on and off with ease but after 2 days of use the top part of the rod became loose and fell off, the other 3 are good it was just the longer one that broke off.
