Product review (4 stars): Bad then Good
I purchased this unit after recommendations from several relatives.  We all have them for our RV's.  When I received it and turned it on, it would not work.  Unfortunately, due to a delay in our first trip after purchase, the Amazon free return period was past.  I checked and found it was going to cost me $70.00 for return shipping.

I contacted "NewAir" and after a two emails with "standard responses," was put in contact with "Mireya" in Customer Support.  I explained the issue and she obtained authorization for "NewAir" to provide return postage.

I returned the unit and "Mireya" notified me that the unit was defective and they would replace it with a new one and ship at their expense.  I received the new unit a few days later.  It works perfect and I am very happy with the product.

Two lessons reinforced.  When you receive a new product, try it out before the free return period expires.  There can always be a defect, but in my opinion, what counts is how the company reacts when you tell them.

In this case, "NewAir" could not have been more responsive and "Mireya" could not have been more helpful.
