DOES NOT HOLD THE BITS THEY FALL OUT

I've bought other extensions of Amazon recently and they ended up being junk, found these and have used them once or twice so far, really like them, the magnetic part of it is strong enough to connect all of the extensions together and can throw it around and they will all stay together (very childish) but it was fun to feel like I had a lightsaber with all of them connected, very happy with this, hope they last a while, and for how much I spent no matter what I think it will be worth it.

You can almost never have too many bit holder extensions, so when I saw this ColumPRO 3 piece bit holder set with three useful sizes I knew it would be great to have.These are your pretty standard 1/4" hex shank bits and come in 3 sizes: 2-3/4", 4", and 6". They feel decently heavy and they actually have very little play. Even when you connect all three together and have almost a foot of extension you only get about 1/4" of play off center. That's as good as I would expect for any name brand so I was happy to see these seem to perform as well. The magnets are strong and hold the bits as good as any other extension I have used. It comes in a plastic case as well which is a nice touch and could be useful to hold these or other small parts.Overall I think this is a great set and a good value for what it is. You also get 3 useful sizes so you have the right extension for each application. Would definitely get again and would recommend.

I ordered this 3-piece quick-connect bit holder set for my “Go Box,” which contains essential tools for most home and auto repair projects.Two standout features attracted me to this product.First, the six-inch length allows access to fasteners that would be otherwise unreachable with a standard-size bit holder. I used one of my new bit holders the other day to install a new toilet paper dispenser. It would not have been possible to access the screws with a shorter bit holder.Second, the magnet strength holds bits securely in the holder and provides rapid bit changeout. The magnetism is transferred to the bit, which holds fasteners to the bit.This product is advertised as having little or no wobble, which has proven true for the ones I received. The shafts are as straight as an arrow.So far, my experience with these bit holders has been very favorable. I am delighted to include them in my “Go Box,” I recommend them without hesitation.

I've been wanting to get a longer extension for hex bits for some time. These popped up at a reasonable price and looked like they had good specs.I used these a few times in the last few weeks. No issues. They fit other bits very well and the magnet holds bits in place even when moving quickly between screws. The external diameter of the round area that holds the hex bits is reasonably stout without being so large as to limit where it can fit.I would get these again and recommend them to others. For the price if you do break one or lose one, they are cheap to replace.

Upon opening the package I noticed one of the long extensions was smooth and round inside where the hex bits are supposed to be inserted, making it completely useless. The other five in the package are ok.

This 1/4" hex shank bit holders of various lengths have already been put through much use amidst my Amish-home to modern-home remodel/conversion. I use them almost daily and abusively so and thus far, they've held up perfectly. Love the size assortment and magnetic holding power. Recommended.

These are decent extenders that get the job done. So far they are working well, one did have the magnet come loose, but I stuck it back in with a bit of epoxy. This set covers a lot of bases, and has been more useful than a single long extender. I've used them a bit as nail punches and they've held up to my abuse well. Price is reasonable for what you get.
