I really love this circulator. It's my second 783DC and the difference is clear. It was hard convincing hubby to go with the 2 large circulators but I felt veryyyyy vindicated today when he said "hmmmmm, it seems these will actually have us using the AC less this summer" . Needless to say I was as pleased as punch. 

I also have the smaller version and I'm seriously thinking of getting another smart large air circulator. Thank you and I love the warranty period. It gives me a huge peace of mind
