its pretty obvious that they cannot try to pass on blame for something you have done for these parts, as all you can do is steam in them. It would be obvious if you had tried to do anything other than the norm like put them in the oven or mistreated them. It riles me that the blades and shaft are not able to withstand the normal wear and tear of domestic use yet they are able to say we have "overloaded" them at one stage or another, and thats all they need to say to cover themselves. When it comes to MC lids and the paying price is only about $15 but the price of blade is about $195 I find that I have little respect for HO.
