I’m giving this a 4 because the product arrived damaged and it was a bit of a confusing mess to get it straightened out. At first they wanted us to send the unit back after it was completely removed from the box. As we all know, this is impossible, but the manufacturer was willing to send the replacement part.  ￼ we are waiting for the replacement ￼part and will repair accordingly. on a positive note this is a great unit for small spaces as this is being used in a very compact apartment in San Francisco.
