I already planned to go with 2 - dual receptacle outlets due to the size of the box I had on hand. The whole build took abut 2 hours and $27 since I had an old 14/3 power cord. Everything is working fine and it was simple to wire. The shipping on the controller took about 2 1/2 weeks. Just under 3 weeks from the day I bought it. It was $19 with free shipping.
