I love it! It's convenient to store, it's quick to prepare, it has a great taste, it has a reasonable price... I totally recommend it over other alternatives I've tried.
The only thing I think can be improved is that I usually store the bags piling them in a cupboard in horizontal position, so I only see the bottom of the bag and it's impossible to distinguish one flavour from another. Identify the different flavours in teh bottom of the bag as well (such as printing the name of the flavour, having different colors, whatever) and it will be perfect!
