Has anyone seen those little immersion water boilers that you put in a cup of water and then plug in and it makes the water boil, for sale in CM? Thanks for any info.

I can't speak for chiang mai, but usually see them on sale in those travelling markets that set up tents each week selling everything from clothes to spanners to household items.

I was looking for a long time too.

I eventually got one in the market at Mae Sai for B20. So if you're going up some time.

Then I did see one at an electrical shop around Wororot market. Blowed if I remember exactly where now, though....

As NL says, they are also in the travelling markets, but not in the one that goes to Chang Kiang on Monday & Friday.
