I'll be in possession of some much newer self serve equipment in a couple weeks. I understand that Magic Wand isn't around anymore, but how much of what they used was proprietary for their self serve pump stands? I see what looks like LED function indicators on their pump stands, but there isn't anything else that's jumping out at me as not necessarily in keeping with the KISS rule. Yes, I see that mentioned often from people on here. Does anyone have any experience with LED function indicators like those? I'd probably be more in keeping with the KISS rule if I didn't plan on replacing the pump stands I currently have with these...I do think the overall outcome will help to simplify things in the end though.
