Query: Probably won't buy this one again...

My main issue is the mixability of this product. It's so clumpy and doesn't dissolve easily. I have to stir and crush the clumps against my mug, and stir and stir some more. The fact that I'm having to consider purchasing some sort of gadget to blend it is not good. I don't want to have to make my morning coffee in a blender. That's just me... Otherwise, there's no after taste and seems to do the trick once you get the clumps dissolved.
