yeah its for 3d objects what I mean is if you use a stereo microscope and then you get a high zoom one (in the 1000$ range) it gets worse the more you go
I think its extremely useful. i mean you either can see it or not see it. with how small everything got, you basically won't say that its a waste of money
100x lets you look at 1 number on a penny. thats still not that small. for really looking at a 0402 part its not like its a bad buy
You just won't see the problems without zoom. see no evil there is no evil?
but there is a problem, the rail microscopes are god damn huge
also, even more zoom, maybe... for looking at glass diodes. just for diodes 200x
