Thank you very much - all of your feedback is highly appreciated, as only this can help us improve everything continuously!Thanks for the insight Alex. I think the pump (and this new interface) are fantastic. Didn't mean to put it down. Everything is "clunky" when you are using it for the first time LOL. But your procedures are logical and no complaints from me. Glad you are working through your supply issues, and thanks for making some pretty awesome pumps!
