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.

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 expected
Been using first and second fixing houses as an electrician for three months and hasn’t broken or even worn down, i’d say it averages about 100 screws a day. Works with my magnetic retention bit too, all edges are rounded so it slots in and out of the chuck well and doesn’t scratch anything up Nice and cheap, give you a bit of range too out the tip of my impact.

Not as good as they used to be
Used to be good and lasted for ages, but now with 2 different packs, they break after a few hours use. Going to use the rest and then try another brand. This is a shame as most of my gear is Dewalt and they are normally reliable.
