Don't wait, buy it as your first balisong trainer, you'll spend money on higher priced balisong later anyway.(and by the time you'll do that, andux will probably have lauched a high end product with a bit of luck ;) )
This is my second balisong and clearly it is a significant upgrade for an extremely reasonable price. The only flaws I could find are the unboxing experience and the material provided, the box has plenty of room to put the spare parts on one side without obstructing the view on the balisong when opening the box, and the addition of a small bottle of locktite would not be a bad idea as the screws tend to loosen naturally after a few minutes of use. (And it would not increase the price significantly.)
The balisong is extremely well made and comes with very little play, the handles lack a bit of grip relief which tends to make it slip easily when held. (compared to other designs of the same price)
Overall:
Price/quality ratio 10/10
Manufacturing: 8/10 (for the price)
Unboxing experience: 5/10
