Well I don't know what to make of it. It is pretty much exactly the same, but then it's just a bit of plastic with a hole in it.
Can you really patent something that is just 2 common parts made into 1?
Not knocking your product man, they do look nice, and I suppose I can understand why you would be ......, but it just seems like a guy has knocked up a very simple thing at home, that anybody with the right tools could do.
There is a thread on here about how to make your own drip tips from a mould. Are they patented too?
I really thought this scene was more about sharing, and people building mods and stuff.
I don't know, those are just my thoughts, probably best to stay out of it lol.
