Yet to use humidifier or would hopefully be giving it another star. Product design and filling capacity seem to be well thought out. Looking forward to trying it late next fall. Purchased to humidify my grand piano in large open room. Thinking it should meet my expectations. Tough to find a humidifier that lasts more than one season trouble-free... yet to be determined. 

Pros: Nice design
Cons: Back ordered everywhere else... must be good
