It amazes me how a company that thinks it's great has to COPY someone elses parts they must be so fucking clever there brain stopped working on that day. And I bet there is fuck all different about them, as for patenting something , it's a lot of cash for little protection but that when ip rights come in and if i am correct the ip rights on the hart plenium ( which are a right which is automatic when you have sold a product so I am told ) so with that in place there maybe a case for the hart plenium to fuck over the very unimaginative airtec plenium which I hope it does as airtec done sod all work towards the development of the hart one, it amaze how they think there so clever , and it will be cheaper as they aint done no research Coz they theived someone elses hard work
