OK, only marginally related to S/P because you can always live without a haircut. But if we're going to rebuild civilization, then haircuts will be part of the formula--unless you're fortunate enough to be bald, then you don't have to worry, you'll always look cool! I highly recommend the Flowbee. I make a little checkmark on the box each time I use it, and with a quick calculation, I see that not only have I paid for the Flowbee in savings, but I'm saved back an additional $350 in haircuts so far! But even better than that...it takes me 10 minutes from the time I think "I need a haircut" to the time I'm done. No driving to the barber. No gay guy rubbing up against me as he cuts my hair (happened once...I got up and left with my haircut half done!) No tipping. No waiting in line. Just hook up and go. Mrs. Bolster swears she can't tell a difference between me cutting my own, and the stylist doing it. Cool thing is, if you use it every 3-4 weeks, it looks like you never get a haircut...always looks the same. OK, go ahead and mock. I love this sucker. I'll be stylin' long after TEOTWAWKI. Trying to figure out how to run it on 12v. I'll be giving solar haircuts after the grid goes down.
