"I've used this, microfibre weave towels & cloths, and Armor All's synthetic chamois to dry cars.
The Absorber truly outperforms them all in my opinion.
-- Microfibre weave towel: great at drying - until they get soaked about halfway through your car dry. They then pick up less, spread water around and don't wring out water very well. Also, they need to be hung out to dry afterward. Not a bad option overall though.
-- Armor All's syn. chamois - not bad. Doesn't slide along a clean car as easily as The Absorber and doesn't seem to pick up as much...but it IS $7-8 cheaper...
The Absorber picks up a LOT of water, slides nicely, wrings well, doesn't harden up of course and truly is easy to store quickly for the lazy."
