One thing, dealing with this company as a paying customer- well both times it has been a horrible experience. I ordered mine in early April and payed for express shipping and something happened (I don't know for sure) that caused it not to move for 3 weeks- after it had been supposedly shipped. And I still don't have it.
I understand things may happen, but when you are lied to and ignored, well what can I say. I'm sure the ap80 pro will be decent, but I will never deal with Hidiz again. My advice to paying customers is stay away. Or at least wait till it is on amazon so you don't directly deal with them.
Or better yet if you're in the US like me, get an hiby r3 pro from musictech and you WILL be taken care of.
In short, with my 2 experiences with Hidiz, if there is a problem, they will say anything to placate you. (but nothing will happen) Then they will ignore you for a while, then promise something that won't come to fruition, then ignore you for a while- then rinse and repeat.
