10x is a joke, i mean i even think 30x is a joke but thats more personal opinion than anything else since with 30x you can almost see good enough to tell how much your trichs are amber but when you go 100x you can really tell what your lookin at and when you wanna pull em Its especially nice because if you know the ripening characteristics of your plant (ie. how fast it ripens) you can lay out your schedule a lil better because you can actually see how much of the trich is milky or amber compared to just kinda being able to see. I have the radio shack scope it works great i just wish the light was brighter like the 420 scope almost makes it seem worth it to me to spend the extra money because that bright white led is the shit. But if you grow inside i like the zorb cause you can bring your laptop right into the room with u and take pics too if you want lol nice suggestion on that one daddio
