la quack has thread-jacked his own thread!!
AFAIK the same China maker makes all the blank modules sold by AixiZ ,o-like etc.
Some will say that those not passing QC for AixiZ go to o-like etc.( I have no idea if this is true) None including AixiZ are perfect which is understandable considering the low cost of these. I have read that the o-likes are often slightly irregular from module to module. AixiZ has to pay more for thiers as they import them to Houston while O=Like is in China. You get stuff faster from AixiZ so its a trade-off.
FYI -- Dr Lava was one of the first to ask AixiZ to get these in numbers that would bring the price down(he asked for a lot GB) ---that was ~2007/2008( i think, maybe even earlier )
Since then AixiZ tells me that they sell around 2,000 blanks every month world wide!!!
AixiZ got started on EeKbay when a larger than needed number of lasers were purchased for one of Dr. Maricles projects-- he listed the extras--they sold fast-- as the rest as they say is history. Beside FeeBay AixiZ has sold a crap-load of stuff on Amazon and, of course AixiZ.com. (which is the only place I buy AixiZ items-never fleaBay or Amazon.
Mrs. Maricle is Xia and thier daughter is named Zi-- thus AixiZ. They pronounce it 'ACHE -ZISS.'(sort of). They are really very nice folks and I feel blessed to be a friend.
