I would like to give Tunze (Roger) the props that they deserve!
As requested above, I sent in both of my 6045s since the shaft had broken in one and the other was purchased at the same time and appeared to be identical. Yesterday, I got a package from Tunze and to my surprise, there were 2 new 6045s in the box. I've always heard they went above and beyond.
Just outstanding costumer service!!!
