I recently used a gem encrusted horn. It is supposed to give +50% chance of receiving diagram and winding keys in both location and puzzles. I couldn't see any difference from normal. In fact in most puzzles, I received next to nada rewards, especially in Mosaic. Several times recently, I have received no reward at all. Feels like a kick in the stomach. Any reward at all is better than nothing. It's not as if it actually "costs" them to give one.

So I think they are a sham. But don't think it's worth contacting Mytona as they will just deny, obfuscate etc.
