The SinuPulse has proven for me to be the best choice. I don't worry about cross-contamination, which has been reported with the Navage. It's better to have all that infected mucus go down the drain than be captured in a plastic canister that you need to clean really well and can cross-contaminate the rest of the unit. I don't understand why folks don't realize this, plus the idea of having to use their own ridiculously expensive proprietary salt pods is a racket.
Pros and Cons:
Bottom Line: No, I would not recommend this to a friend
