These 16.2 packs are a headache. The simplest way to use them is make 2 jugs at a time, which is inconvient for all kinds of reasons.
The Ziploc makes cutting them open messy. Often not sealed, means powder all over. Seems unnecessary expense. How many people reseal these bags?
Narrower bags would make pouring into the jugs easier. 1 bag, 1 jug - no mixing, no measuring, both jugs don’t need to be clean at the same time, one can be in the dishwasher.
The unnecessary inconvenience is a barrier to use of the product. I consume less because of the effort (and sometimes messy annoyance) of making the stuff.
