Honoson12 Pcs Drill Bit Extension Magnetic Drill Extension Bit Holder 1/4 Inch Hex Shank Automotive Quick Release Screwdriver Extender Adapter Set for Screws Nuts Handheld Driver 3 Sizes

The quick connect did not work w drill bits from amazon or milwalkee or harbor freight but they worked w other shafts from the set. Much cheaper than bosch quick connect which worked w all drill bits and fits into maglite

It's good but the blocking device does not work perfectly

I got these for use with my drill driver, and drill guns. This set is cheap and you get a bunch of the locking bit drivers. The problem is that they don't last long. The locking feature on the bit driver extensions are the failure point. The driver extensions fit perfect in all my guns and all my bits fit perfectly in the extension. The spring loaded locking feature on 5 of these have already failed. The strength of the extension itself is enough for me to drive 3" decking screws continuously. But w/ repeated install and removal of the bits, the locking collar and spring have repeatedly failed. I have a few left but poor outlook on their future. I'll likely get an extension with a more reputable name. Can't recommend this set even if it was cheaper.

Came as described and on time

I typically use the Dewalt brand bit extensions, so I guess I’m used to the spring loaded release. With these, the magnets are a little weak compared to others and you can’t do it one-handed release of the bit. So far they are holding up and if you’re not swapping out bits regularly, these are a great option.

So far 2 of them broke since I had them and that only the locking spring. I do wish it was magnetic so it would hold the bit. But they sent somany that I have replacements

Good quick change bit extensions.Came in x3 pack of x3 sizes.Great value and decent steel material used for the tool.

Priced cheap, several pieces included, 1 of he small extensions would not work, looks like the machining has metal sticking up inside preventing the locking mechanism from allowing you to insert anything. I did not feel like sending the whole kit back, so I just threw it out. Also could not find customer service POC for the company.
