I was skeptical at 1st, honestly. I didn't know how a control box operate, let alone install the wiring to one, a bit intimidating I thought. However, this Vevor.com 1.5 HP 110V 60HZ submersible pump with an extra long wiring harness, control box and outlet spout attachment with O-ring was very simple to install. Easy-to-install, quiet functioning pump and with extra long wiring harness makes it a snap to install the control box in an accessible area. Another plus is the the lighted "On-Off" switch, which when the cover is removed to connect the wiring from the pump, there is a diagram on the inside of the cover displaying the correct wiring schematic. This submersible pump, rather than connecting the wiring to an idiot mechanical pressure, connects to the Control Box which plugs into an ordinary electrical wall socket. The pump itself is a bit heavy and rightly so. Smooth stainless steel housing feels good in your hands and should impressively operate for many years to come. Performance of the pump is quiet. The pump delivers much more water pressure than the previous two HMs installed less than 4 yrs ago. Delivery was 12 hrs early or say one day early. The package was a little worn but no defects to the product. This Vevor Submersible Well Pump 110V 60HZ receives 5 ***** in every category
