I hope you had better luck than I did with the Sofielite. I purchased a Sofielite unit from Peter Schiff Aero and immediately had problems. The unit would leak water and spit water out of the vents. I contacted Cole Schiff and he had me perform various tests which I did, and videoed these and sent to them. Eventually, they grudgingly agreed to take the unit back to repair. After four weeks, they decided to send me a new unit. At first it worked, but after a few weeks, it began doing the same thing as the first unit and spitting out water and leaking. Peter Schiff then entered the conversation. He acted as if they were doing me a favor to fix the faulty unit. The conversation quickly went sour, and both Peter and Cole stopped responding to my calls and emails. Since this experience, I have found many others reporting similar functional problems with their units, lack of integrity (not honoring warranty), and zero customer service by Peter Schiff Aero. Poor product and appalling customer support. Lawsuit to follow.
