3300 Grid Doctor

The Doctor is in! I picked up the 3300 solar generator during the 4th of July promotion with so many other supplies included. I could not be happier with the service and products. I have already used the generator twice with one power outage and for a power source to cut up long pieces of wood I bought to fit in the car when my pick-up was in the shop! I ran my small house on the 3300 for 5 hours which included lights, fridge & a deep freezer as a test. I will use this in conjunction with a gas generator and not have to depend so much on gasoline for long outages. Thank you MPS for a great product!
