Could be due to faulty memory circuits, but overall... I think I've seen more good, or at least halfway decent personal reviews about Aixiz across various sites, than bad.
Funny, but Illuzion essentially states the gist of my impression of Aixiz thus far... The customer service is friendly, and helpful. Things may move a bit slow at times, but seems they always come through to do the right thing. Again, that's just what I seem to remember. Haven't actually sought to read up on what's said to be "bad" experiences.
As for my personal, but non-direct experience, I'm quite happy the deals they've provided in regard to a couple group buys on CPF. Both times involved their case/lens modules at excellent prices.
Alas, poor diode. I fried him well.
