I've tried just about EVERYTHING, including what one dealer told me was the best, a SRA (squared series) and this wasn't even close, it paled by comparison to the Vibraplane. I bought one Vibraplane, then another Vibraplane, I now use 4 in my system. Deflate them and I can not listen to the system any more, it is that drastic.
Don't listen to dealers, they are used car salesman, listen for yourself, you will HEAR the difference.
