Yeah my experience too is that the non dairy creamers.... taste very much like non dairy creamers.

That's not necessarily bad if you like that, there are lots of product substitutes that to a good job in their own right even if they aren't what they intended to replace. I cook and there are all sorts of good products that historically were intended to replace or augment something else and do their own thing well.

But as far as non dairy creamers go, it's just no a replacement for actual milk for me. Two similar, but noticeably different things.
