    Motor current = 0.9 amps was missing on the description.
  

*by J***S on Reviewed in Canada on 13 April 2024*

Motor current = 0.9 amps was missing on the description.  However I was able to zoom in on the nameplate where I found this info. All other information on the description  was accurate including the reversion option which is as easy as it can be.  Very happy with it.
