Although canned air is a luxury for those who eat while they surf, wouldn't it be wonderful if you could get one that never runs out? You practically can with the rechargeable Hurricane 2 Canless Air System. You get over 500 full charges, the equivalent of about 20 cans of air per charge. That's 10,000 uses! Because it has a wind speed of 150 mph, so there will be some noise but the device can be used at any angle so that seems a fair compromise.
