Well i have gotten a system, which a few weeks later i had to put another lens in ( sent to me )
That was the mini 0906
A system i also managed to "destroy" pretty fast for the first time, otherwise test samples seem to last fine for me.
With the joovuu X cam my 2 pre production cameras almost also lasted as long as the production sample, though the very first one as i recall was not covered by later firmware upgrades as something had changed inside it.
Even if the mini 0906 died suddenly on me, right up until then it was working well and i was fairly happy about its footage.
My very first SG camera the SG9665GC V1 i also had to adjust the focus on after a little while, but then it also worked fine and it is still working though it is now a backup camera for my friend that run the SG9665GC V3
