As for contact info, I prefer PM. I have no desire to post my e-mail address in a public forum. I will give it out to any serious buyer.
Please research before contacting me. There are many threads about this device on the forum here. There's a lot of controversy about these (and especially the company that made them) and I would prefer to sell to a knowledgeable buyer. As stated, it worked great for me. Not trying to be a jerk, just a conscientious seller.
If you have a valid question about my experiences with it, then I'll be glad to answer. If you don't know what it is and can't be bothered to look it up, then it's probably not for you.
