hehe...somebody doesn't want to read the patent...
the patent has been broken down by folks on this board way smarter than me. i believe a fair summary of these evaluations to be: it works, and it's a steal that Dean was able to get a patent on this as it will be greatly difficult for other OEMs to get around his patent.
please do some research--even if it just means reading old posts--before you post untruths.
and no, i'm not going to go back and find those posts for you. they are here for those that are interested. do you own DD.
