Hello there,
I do not know what all have against the stem. It is when one assembles it properly, very stable and robust!
Customers who complain about the shaky stem have, quite simply inadequate and wrong assembled him!
You have to put together the 3-part handle ....... and then IMPORTANT !!!! screw clockwise.
Thus, the clamping mechanism pulls apart and connecting the handle elements firmly and stably with each other !!
For the system there by me full credit, price performance top! =)
