10-Pieces Magnetic Bit Holder Extension, 1/4 inch Hex Shank Heavy Duty Quick Release Screwdriver Drill Bit Holder Extension Set for Screws, Nuts, Drills, Handheld Drivers 50/60/75/100/150mm

I bought these as back ups in case I lose my extension bits. I haven’t used them yet, but I’m more than sure that they’re gonna work the way they should.

You get a lot of extensions for your money with this pack. The set comes in 2 cheap ziploc bags but you're not buying these for the packaging. The steel looks to be adequate but clearly not high end. Because these types of tools are often lost or abused, the low price may be the greatest strength of this set.The sockets are rather deep which is good for attaching extensions together for greater reach but bad if you are using a short bit. (it will swallow most of the bit making it difficult to remove)These are not high end tools but they are cheap. There is no lock on the socket, the bit is held in by magnectic force and the sockets do not appear to be hardened steel. I suspect these will not take a lot of force before they fail. You do get two of each size.Bottom line - If your work involves the possibility of losing a tool or two, these may be just the ticket. I'd rather lose a $1 extension than a $10 one. If you need a good quality extensions for critical work, these are not your best choice.

Hold the bit well. Magnetic is good.

I was excited at first but after using the bit extensions the 1st time... The magnet that holds the bit would fall off and I loose my bit... Long story short every single one has the magnet fall off and I lost the bits... Would never recommend. Just spend the extra $ and buy from a reliable company

Magnetic tip is average. No hog ring for bits. BITS WILL COME OUT afterwards. Can be annoying when attachments come off in a confined area attaching hardware.

Needed longer bit extensions. Good price

Ok

Not satisfied with magnet retention.I needed to add my own glue!
