### ⭐ 1.0 out of 5 stars







  
  
    Buyer Beware!!!
  

*by D***E on Reviewed in the United States on June 25, 2016*

You get what you pay for! Mine arrived with all metal tabs bent over. I was installing the knob ( which does not hold the shaft very well ) when I accidentally overturned it beyond where one of the bent over metal tabs would normally stop rotation and the small metal block popped out of its enclosure. I got it back in but again the general construction of this rheo is dodgy at best. I would not recommend it to anyone unless you only need one for extremely light use or perhaps a demo.
