I normally buy them in LARGE quantities as it seems cheaper. Buying them off ebay in the middle of winter also will snag a deal from time to time. I have a couple of the portable devices and one of these. As long as it's not windy (if it is, put them down wind or on the ground near you), it does an ok job. The non-smelly disc's work better IMO but even though they say mosquitoes don't fly in windy weather or when it's cool out side, I've seen those pesky little beasts when it's 40 and 20mph winds. I think those are the ones visiting from Maine or Minnesota.
