Bought it last summer and used once, all bottles with ~ 1 oz or less removed. Will also throw in a 50% used Menzerna auto shampoo and two new microfiber applicators.
I'm selling because I have both Menzerna, Klasse and Blackfire lines. Trying to consolidate. Since I only really detail my own car twice a year, all of the LSPs seem about the same within a month or two and there's simply no way that I'm ever going to use all of it.
