Well, I went ahead and ordered it. Had to run through the usual routine of infomercial companies trying to sell you additional stuff. It is only $10, but it is $10 for two. And there is no additional option, unless you want additional BOGO sets. Then they charge you $7.95 shipping and handling, and that is per set. So my total for 2 came to $25.90. And that's fine with me, as long as it works as advertised. Now another funny part is they tried to sell me the Deluxe package, which they say states will for over 3,000 times and also comes with the lifetime guarantee. But if the non-deluxe item has a lifetime guarantee to stick, then why would you need the deluxe version!! That was $5 more, but I opted out of that.
When it does arrive, I'll report back here with my findings.
