3pcs 80/120/140mm 1/4" Hex Shank Bit Holder Extension Quick Change Screwdriver Connection Rod Adapter Sleeve

They make work much quicker and easier.

Bought these to replace a Dewalt one that blew apart after several years of use. These 3 cost the same as 1 Dewalt bit and as far as I can tell are equal in quality. The magnet holds the bit strongly enough and the sleeve spins freely. I am quite pleased

These are not worth your money people. The sliderComes off pretty easy one came off the very first time I use it. Let me tell ya I’m no stranger to theseThing so I do know how to use them. But it slid (not all the way) off and once it does that u mite as well throw it away,if u do manage to get it back on it won’t be worth #%€£

inexpensive

Great price for a quality product

These extensions are really awesome. They make it super easy to drill a screw in without it flying off the tip of the bit. The price is great and i'm hoping they last a long time.

Not magnetic, 2 of the 3 broke within a couple weeks. I wound up buying a different brand.

Used the middle type for screwing fence screws but it broke. The others so far are ok.

The sleeve comes in very handy, saves your fingers from getting cut by the threads and holds the screw when in awkward positions

Was supposed to be magnetic but certainly are not, one of them sleeve it loose on bit so bit awkward to use.

The magnet is not so great and i do not understand the design. More details in the picture, i used the same bit ( it looks like it is extending) . It is broke or that's how it should be?

Thay are not straight no good what so ever

Do not buy all broke on first use the shaft rotates within the body leaving no rotation on the screw
