This unit was bought from a box stores site and delivery was supposed to be 5 days later. It ended up taking 13 days, but thats not on Westhinghouse and instead the shipping company's fault. Since arriving, we have been doing the break in period and its working great. We are going off grid for 8 days next week and that will be the true test, but if how its worked so far is any indication, it will be a flawless trip.
