Men are not the only ones who do this. Yes the name comes from a male biased behaviour in the tech community but I have witnessed plenty of this out in about in non tech fields... "oh your an man, there's no way you would understand" or starting to explain something before asking if I need an explanation how it works, because why would a man ever need to know how a thing, like say a sewing machine, worked...
Calling it "mansplaining" (which is in my iPhones dictionary!?) does nothing to help stamp out this behaviour as undesirable. It arguably provides excuses for women to engage in the behaviour since they aren't "men" how can they be "mansplaining", and contributes to its continued existence by allowing this "mode of interaction" to continue regardless of gender.
Other than that. Awesome company, and I hadn't heard of the product despite having a need for something like that. So I may buy that milling machine in the future which is pretty cool.
