About a month ago I ordered 5 samples for about € 26,-. The samples I received were all about 60% filled. I wouldn't call that very generous. That said I liked L'Air du desert Marocain and Une Rose Chypree, but not enough to buy them. I thought I would love Incense Rose, Incense Extreme and Reverie au Jardin, but I didn't like them at all. Imo Andy Tauer scents are very overrated. They all seem to have a kind of (similair) spicy edge to them that only seems to work for L'Air du Desert Marocain.
My vials were full. Sorry that yours weren't.
As far as his style: yes, it's very distinctive. I find it somewhat "wild". People tend to either really like it or dislike it, it seems. I'm in the former group.
Mine were full too. And I like that he uses glass atomiser, let alone the neat tin box and personal touch.
I'm not done with sampling yet, but I thoroughly enjoy the ones I've tested so far; some are nice and others rather excellent, imo.
As for his style, I agree, Sherapop
, the so called Tauerade is indeed distinct and might not be as versatile as, for instance, the Guerlainade is.
