I was skeptical at first. But they work as expected. Each tablet is individually wrapped and packaged in a ziplock bag. One tablet per gallon of water, and in 15 minutes you'll have blue washer fluid. With 50 tablets I'm set for years. I no longer have to lug these containers out of the store and love that I don't have to keep large gallon jugs in my garage or car. It just makes sense. Just be careful if you drop a pill or two in the glove box or console, as each pill is neatly wrapped in silver packaging that could be mistaken for candy. There are no markings on individual packages. I slipped a few into another clear zippered bag, wrote "windshield wiper fluid tablets" with a marker, and placed them in the car's console. After using multiple tabs Update: You don't have full cleaning power if a gallon of windshield washer is bought at the store. Heavier dirt or insects cannot always be removed from the windshield. I will double the number of tablets per gallon to see if that helps. Even using two is a huge savings.
