A Japanese company named Kuchofuku, invented a cushion that can provide 170 liters of cool air at the bottom through the built-in fan Per minute, so your back and butt will stay cool during the hot day. Because the company want people to feel the benefit of this gadget wherever people set on, the company created three different versions of this cushion. The first one is the standard version which was made by Super Spacer material, and built-in battery; the second one is the High Grade version which was using double Super Spacer material, and built-in touch sensors switch and battery; the last one is for the car seats. People can purchase this “helpful” gadget online now for U.S $89.00. For me, this gadget seem great but in fact it is stupid. Why should people buy this thing for $89 but not a cheap, big, powerful, and cool fans that they can get easily in Walgreen, Best Buy, etc. New invention is great but do not invent something that is useless, pointless, and most importantly expensive. If this gadget only cots $10 to $20, I might give it a try.
