I unfortunately cannot discuss who we do and do not private label tools for.
For the ones we do not private label, I anticipate there will continue to be several mini impacts getting to the market that are aiming for our design or something similar, because it's well known at this point that it sells and performs well. However, if I'm honest we weren't the first one's on the block with a mini impact either - so it's not fair to say they are just copying us.
As for the housing, unfortunately or fortunately depending on how you look at it, you can now find these everywhere in Taiwan. There are a handful of outfits offering this same shell for many air tool factories to utilize at this point. The way around that is to make a custom design casting that plays on your brand's standard design or logo - but that delays the product hitting the street and has to be baked into the cost. We usually reserve that route for some of our private label customers.
