But Andy, understand this: Fluenz Mandarin 1+2 & 3 is the work of a genius, but it is clearly an unfinished product. Those who have completed the entire thing have been left at the doorstep of Lower Intermediate Level. I have compared almost every Mandarin course out there from some of the biggest companies and none have the level of sophistication that Fluenz Mandarin has. I have even purchased and then thrown into the trash can these other Mandarin courses because they clearly are lacking in every way possible. The ONLY shortcoming with Fluenz Mandarin is the lack of Levels 4 and 5. For a company as huge as Fluenz to have created THE ABSOLUTE BEST Mandarin language course out there and to then stop short of the finish line is similar to producing the greatest bottle of red wine and then after opening the bottle and letting us get a sniff of the wine, not having enough glasses to pour the wine into. It is a tragedy. Surely a company as big as yours can assemble a team and give us levels 4 and 5. We are willing to pay for it.
