Top quality
These bits work well and last better than others had for a while now and still using these same ones and only 1has broke so these are good quality and quite fair price As I use them every day I will definitely buy these again

Good enough works well
It's not a bad product, I used one of the heads maybe 6 odd jobs and just snapped on 2 parts of the polz head yesterday. Not bad quality all things considered. It's like everything else in how to connect and all universal the fact its a long neck on it helps on many tasks to reach for install where as using a ext bar isn't always possible. Seems to give a stable contact point when used on my impact driver. The negative i suppose is nothing unique about product so if I need replacement parts I tend shop around for best price for that type of criteria

As Good as Anything Else
In my opinion, these are no tougher than other bits I’ve used but they do the job as well as any other bits I’ve used. The great thing is they lock directly into my impact driver removing the need for a magnetic bit holder. This means you don’t periodically leave the bit behind, jammed in a screw head.

Not good
Not what I expected from dealt the bit shattered the first time I used it after only 6 screws
