Review on 30 Pcs Magnetic Screwdriver Bit Set 4 Inch, Mixiflor 1/4" Hex Shank S2 Steel Long Drill Bits With Storage Box (Slotted+Cross+Square+Torx) by Bart Schwalbe

This set of the 4 most common driver types is nicely laid out in a red and black case with elastic bands holding the bits in. They work with any impact driver or standard drill and the metal seems fairly durable although I'm not sure I'd use these for heavy duty use. Nice to have when you need longer bits, and they haven't stripped at all in my use with them. All bits are clearly marked on the bottom with their type and size.The tips are slightly magnetic, they hold most screws on but it's not the strongest magnetism I've seen on a driver bit. I'm happy with this set, I didn't realize they came in a case and that makes it a lot nicer to keep them organized in my tool chest.
