Has anyone used an inflatable "pro-collar"? Its like an e-collar but supposedly more comfortable?

I have an 11 pound shih tzu and i was wondering if this would be better and more comfortable for him to use rather than the plastic e-collars...
has anyone used this before?
Answers:
Yup. I really liked it. I liked knowing my dog could actually see. The only problem is a neighboor dog came over to play and chewed it up. (stupid dog)... but the other dog would of chewed up the e collar as well.
