Yakamoz 16Pcs 4-in-1 Multi Long Magnetic Screwdriver Bit Set with 1/4" Hex Shank Drill Screw Driver Bits Power Tools Kit (Hex Head Allen Wrench, Torx Security, Cross Phillips & Flat Head Slotted Tip)

Great

I bought around 5 brands of sets some even cost me +40$ , and none was as good and efficient and appropriate to work with as these !! Very happy with it

While shopping for long driver bits I was surprised by the number of reviews that said their bits were "bent". So when these arrived, I put them in the handle and the tip wobbled. But then, I used a dial indicator and measured them to be quite straight. So, I measured the base, which was practically a perfect 1/4", but the socket on the base was .050" oversize! So the bits wobble a bit. This mismatch is not an error on the part of the handle manufacturer, rather it is intentional to make insertion of the bits easier. You don't see the wobble in shorter bits, but with this long lever, it becomes obvious. Once you have the bit inserted into the fastener, so that it is fixed at both ends, the wobble disappears. These work just fine.

So far so good and do the job. Seem to be a quality product so far for a special purpose.

Excellent quality and well worth the cost. The longer length is definitely useful. I've added my more commonly used bits to my EDC kit.
