Review: Junk - 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.
Review: Only good for lightweight work.... - Poor quality - 1st time I used it, the end became loose from the shaft. So it holds the bit, but the bit just spins freely. I guess not designed for any heavy torque usage.

## Features

### ⭐⭐⭐⭐⭐ Good set. Expect limitations.
*by C***L on September 22, 2024*

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.
