I have the impact set, they are alright. As far as the impact goes, it's nothing special. Don't expect them to work on really seized screws where you would normally use a handheld impact driver and a larger hammer. I don't regret getting them on sale. As far as the dual tone ones go, I couldn't bring myself to get any. They remind me of some sort of alien/dragon/anime *** toy. Tentacle **** comes from the same place so you can see where they took their design cues from
