I was really impressed with this.  There are many flavors, and quite a bit of heat.  With this and your favorite brand of cocunut milk you can make some great Thai curries at home.

I didn't like the taste of this product - couldn't finish it off because it was a little metallic tasting and had an aftertaste.
