I mean...if you just put a regular fan at the right angle wouldn't that suffice? I cant imagine that such a low powered fan on the inside of the suit could be much more effective than a semi-powered one angled well.
i take mine off in the shower. That way it gets rinsed off. If you dry it inside out it feels more comfortable putting on (because its dry on the inside) and is easier to get on because the fact that it's wet on the outside gives it more flex.
For less than half the $$$$ you can make an even better device at home depot or lowes...and it will last twice as long. Buy a small 8" clip-on fan and some pvc, and in 10 minutes walla! If you want exact details email me, as I've done it for myself and several friends. On the flip side, if you can't cook toast, pay the 50 bucks!
rinse it and hang it correctly immediately after surfing.
hang it outside in the breeze or if it's too cold out hang it inside in a well heated area.
then just keep turning it inside out and back over and over.
