I bought one of these a while back (2014), and overall found it to be a great product by looks and functionality but it falls flat on quality. Especially on internal quality – after about a month of using this device, one of the side buttons stopped working and upon inspection (inside) I saw just how flimsey the plastic switch support mounts are. Very very fragile and given that the particular button was a seldom used thumb button and how it sheared off it's crappy plastic button mount I quickly lost faith in the whole product and would NOT recommend it to anyone especially those who might be a little heavy handed on the buttons. They cannot be repaired once the mount point breaks off. I may have been unlucky with a bad factory release, but if they fix the internal design to be more robust it would be a really good controller since all the buttons are at good reachable locations and there are enough of them for most flight games plus the price is excellent, pity the manufacture isn't.
I paid $AU89 and chucked it in the bin after it broke (after a month) since it couldn't be repaired.
