I’ve been using my Van Gogh unit for 18 months and have had no issues.

had one small question that came up while cleaning it yesterday in between oil scents. CS rep Geovanny Galvez spent 15-20 minutes on the phone answering my question and then going step by step with me to ensure my settings were all correct. Come to find out they weren’t so his offer to double check with me before hanging up was very much appreciated!

The unit itself is fantastic. I do not have it hooked up to the HVAC , so it functions as a stand alone unit. Despite that, it adequately scents our almost 6,000 sq ft home efficiently. I added fir tree scented oil yesterday and the whole house smells fantastic and like Christmas!

I would like to add a tip to those who are sensitive to smells or migraine sufferers like me. You can purchase a non scented oil called Diffusol to dilute your scents down a bit. I learned this from a different CS rep after I first got the machine and was suffering even with the concentration setting set low. No more problem!
