It's okay.  Low price. It doesn't feel real sturdy, but only time will tell how it holds out.  For now it does the job.

Update; so I guess you get what you pay for.  The Knob's aluminum ring and cap came off twice. I don't have a dishwasher so it has only been hand-washed. I put it back together with super glue and it's staying on so far.  Crossing my fingers.
