Daman 10pcs 5-Sided Screwdriver Bit Set, Magnetic Drill Bits, 1/4 Inch Hex Shank Bits, Security Tamper Proof Screwdriver, Pentagonal Screwdriver Bit

I bought this product to adjust a new bike. They were accurate size and high quality. These were easy to use and good value for the money. This performed exactly as expected

Unique tool that comes In handy.

Item arrived in a timely manner. Well packaged. Sizes are accurate. Functions as expected.

Bits worked fine. Unsure of how strong or strip resistant they may be, I only needed them for a small job on my car, but they seem to be as good as any drive bits out there.

Had to buy this entire kit to use one size, one time.. but it worked!

I was tasked with replacing a commercial TV and found that it used 5 point security bit. These had the correct size and worked. No issues.

Needed a new rechargeable battery in a Bose bluetooth speaker a friend gave me. 5-sided security (hole in the middle) screw heads needed. Bang! About 15 bucks for these heads, 15 for the new battery. $30 to save me, what, $200 for a new Bose? Done deal.

These should have size markings on the side or at least somewhere on the bit but there is nothing. I would've been nice to seem the sizes to compare their accuracy to other brands. The bits did seem sturdy and durable but did not work for my application so they were returned.
