I like the low power draw- . 68 amps, 90 watts and the large amount of vibrating power output. The vibrator is very well constructed and seems dust and water tight. I am building a heavy minerals concentrator that will operate dry and the powerful vibrations will take the place of water to move and separate them by their heavy specific gravity differences. This will be a very dusty environment, even being operated outdoors and this unit has the looks of a machine that can last a long time even under extreme conditions. I am very happy with this purchase and this exact unit will be my go to machine for prototypes moving forward.
