They have some decent products. The clay is great, WW MF is decent, spray QDs (acrylic, acrylic spritz, and carnauba spray) are all good. Sonus Cockpit is pretty close to 1z Cockpit. Leather cleaner and conditioner are great as well. Have not used any of the polishes or anything like, it is a good line but there best prodcuts, IMO, would be the clay, leather products, and QDs.
The Sonus pads are some of my favorites. I also like the Sonus green clay, waffle weaves, and Carnuba spritz.
The older pads where really good, the newer pads done seem to work as well as those original older ones. Which ones are you talking about?
The Sonus Der Wunder waffle weave is good. The first few I got were excellent, then I received a few that were duds. Supposedly they'll send me some replacements though, which was good customer service. But apart from that, haven't really used anything else.
