Why waste money on Coway? Boil own water or use a microwave to do it.

I sometimes will microwave water for coffee or tea if lazy. Only 3 minutes with a microwave safe cup.

Boiling water over a stove is also easy. Just find a stainless steel kettle. Plenty at household wares shops.

Electric kettle also can but in experience, always kaput.

i wanted to say so but i can't imagine got lazy people boil water using microwave.
