In my experience, 3 things impact the quality of a spray tan:
1. The
equipment itself and it's delivery system
2. The solution used
3. The training/education given to the client in how to do it properly to get the best results including use of barrier creams, proper stance, toweling procedures, etc.
I've been using the Mystic for almost a year, with the Premium Bronzer Mystic Tan solution only. No orange for me or my clients when step 3 is followed correctly. However, I do notice that in the winter months, I think the Level 1 looks more "natural" than the Level 2 I normally use in the summer.
