I just got a new kit - I have been using this for over a year and it helps so much? The new kit has square salt packets - and I have to tell you they are a pain. I end up spilling the salt as I try to our it in the bottle. The old packets were rectangular and made it so easy to pour the salt in - I never spille it. Why the change? Thank you.
