I think fair play for including an adapter, to use with a product not made by MH, also adjustable so that other dhv can be used.
I get that it could move if carried in a bag, but ..
don't think you can please all the people all the time . This is Brenyo's solution is all.

I didn't even get any extra screens when I got my Anvil or Tornado.
Only time I've got a sleeve/ case when buying a dhv was with the Tempest.
Still waiting for my Grasshopper case which I ordered at the same time as my Grasshopper
Labetkomp makes some sweet leather cases
Think Brenyo said he has a tube in the works.
Performance, to me, was ultimately more important than any case, which I may or may not use.
Hope you enjoy getting to know your Tempest
