I use these with a ratcheting driver set so I can get to those areas too narrow for a stubby handle since the collar on the driver is only 3/4" long. This set was less than a buck more for a single 6 inch extender. It's like getting two extenders for a buck more than one. Well, almost. The 6 inch extender is 5-7/8", the 4 is 3-15/16", the 2 is 2"(maybe 2-1/32"), to be more precise. The collar on each is almost precisely the same size, 1-5/16" (within 1/64"), but the shank is likely not uniformly set from one pack to another, so each buyer is likely to get slight variances in length of each extender. This seems true for most extenders on the market. For me, I was able to get 5-5/8" from the 4" and 2" extenders combined and 11" from all 3 extenders combined, give or take 1/32". All measurements are made without placing them in the driver. The best thing about this set over an individual extender is the ability to mix and match for different lengths. The 2 and 6 make 7.5", the 4 and 6 make 9-7/16". That's 7 different lengths from a set of 3 extenders. So if you need more than 9" for reach but less than 11" for total space, you're covered. They are also good for quick changes of hex bits with power drills (especially if using hex shank drill bits and driver bits back and forth for setting screws; much faster work). The shank ends of the extenders wobble a little in a standard hex driver just as they do in each other's collars, but that is expected from any hex bit (just more noticeable because they are longer). The magnets are good enough to hold the weight of each extender in any configuration while aiming them down and shaking vigorously, even with the wobbling, so good for standard bits too. The collars themselves are not magnetized so don't think they will retrieve lost screws, they're not designed to. I have not used them to tighten anything too much or loosen anything that was really stuck, but they are easily as capable as anything else I own in this price range. These will never replace regular screwdrivers for getting into small holes that are recessed since the collars on bit drivers are just a little too big around (3/8"), but hopefully you already knew that; better to buy long screwdriver bits for those jobs. These came coated in some kind of smelly oil like many other tools that evaporated once unpacked for a few days. Now they are like everything else in the toolbox. Would buy another set for friends/family.

Very convenient to have in my drill/driver carry box. Good quality and a strong magnet.

These extensions run a bit eccentric but contained a shorter than normal extension which is what I needed. The longest is the most wobbly and does best at slow speeds. Someday I'm sure I'll find a real use for it. This review asked about the level of Sheerness. My X-ray vision is no longer good enough see though the outer steel so I guess they aren't sheer enough for me so it wasn't worth knocking the rating down for that. Odd thing to rate for a bit extension.

The power of the magnet is weak. Regardless, it's a useful extension. We hope they last.

This is exactly what I was looking for and for the least amount of money possible. As a newly single gal I have been forced to buy tools in my new home. My ex had every tool ever made, that was nice. Now I love shopping but not for tools and man stuff. These worked for what I needed and I have used them several times without fail.

The 6-inch magnetic extension wobbled badly in my drill. When I examined it closer, the hex shank appeared to be slightly bent. I then placed a machinist metal ruler on the hex shank and confirmed that it was indeed bent. This tool is useless for its intended function. DO NOT BUY
