Well, I finally heard from flow last Monday morning (Saturday afternoon now).
They asked for the āFlow Frame model numberā.
I replied and supplied that to them on Monday morning.
Iāve had no reply back, no information, received no parts and have absolutely no idea what is going on and whether they intent to send the missing covers - or when.
Itās now almost two weeks since first contacting them.
It is really a let down after the excitement and interest I had in this product.
Itās now so late in the summer that by the time I get my frames workable there probably wonāt be any point installing the flow super until next spring 
Iām in Australia, near the coast between Sydney and Brisbane (where the factory is) - so hardly at the end of the world. Itās on a 1-2 night standard post from there to here.
