Yes, I'm using the Korean-made one bought from CWB City Super. I think it's quite ok - even my hubby's sweaty T-shirts lose the smell after washing with it (no detergent or softener used).
haha, it sounds very high tech - it is supposed to break the water molecules into smaller ones and therefore can get into the fibre of the clothes. It was around $450? don't quite remember. supposed to last for 2-3 years. www.well-tec.com.hk/php/big5/index.php
