I also love the product/s especially Optimum Hyper Polish, and completely agree that the sprayer has been and is still such a pain to use, that I just shook up the product a lot, and transferred it into a Meguiars plastic bottle with the tip that you cut off and put the little red cap on, and its been great.
Since that time, Meguiars I believe has come out with a newer plastic bottle that has a flip up self cleaning tip which should be even nicer..
I talked to Optimum about their sprayer bottle, totally understand their intentions for making it, (and they even replaced the sprayers for awhile), and it looks like they are standing by their intention to allow the user to spray their compounds directly on the paint or pad.
While I understand their intention to do this, I will never be personally happy with the design which I have found to have challenges for me and the way I like to dispense product while I work..
