YIYITOOLS Screwdriver Bit Set 45 Piece

I think the red is misleading, cosmetic only, meant to imply the bits are designed with a “torsion zone” like quality bits from Milwaukee, DeWalt, Bosch, even Ryobi (in long sizes only). These, at best, are S2 steel and probably “impact” in name only and of dubious value for the price. Many positive reviews are of FREE products, others question durability. Assortment is good, more variety than most and case is very good with rotating rows. My fault for not reading descriptions more carefully which aren’t specifically false so I’ll probably not return but I’m very disappointed that they’re not really impact bits as I inferred.
