Great Bit
These BOSCH Phillips/Square #2 bits are excellent quality. The fit is tight and precise, which helps prevent cam-out and stripped screws, especially when doing repetitive work. I’ve used them on electrical installs and general construction tasks, and they hold up much longer than cheaper bits. The durability is impressive for 1-inch bits — even after heavy use, the tips stay sharp and don’t wear down quickly. They also lock securely into the impact driver with no wobble. Overall, a great value for the price and definitely a brand I trust for daily use. Would absolutely buy again.

Best bits I've used
These grip a Phillips screw better than any other bit out there. They are a bit faster wearing than other bits but it's worth it for the performance when they're new. They also fit a Robertson (square) drive screw quite well. I'm an electrician, a lot of screws we come across are Robertson, on top of how well they grip the screws, it's nice to have a bitbthat fits multiple types of screws.

youtube hype
i’m an electrician and i saw videos in youtube about this bit that it’s the best but i was disappointed about the hype. it was good for a few uses but it didn’t last long when working on heavy duty stuff. it’s probably only good for light work. just get a more trusted brand
