Hi one step ahead.com (can't remember if its all one word or not). I got 2 there last yr and used them in our camper for the boys bunks,cuz I kept forgetting them in the parks. Just make sure you bring batteries! They do work great. My other trick I learned of the boards was to ask for a cup of Ice (it's free) then I'd bring sanwich sized ziplocs and fill with ice wrap in thier blanket while they are napping. It worked great, it was 95-100 last oct. I did this everyday after the 1 1/2 yr old woke up I'd plop it on the 4yrs old head to cool him off. Have fun anyother ?'s i'd be happy to help.
