- verified customerAlthough it is no substitute for an actual microscope, I'm still happy with this acquisition because it fills a need for pocket-sized, ultraportable viewing.I haven't yet analyzed large-sized burrs, but it's shown me some of the bigger microburr whiskers while uncomfortably close. Uncomfortable because my eyeball or face has to be adjacent, an inch or less away, from the sharp edges to get the best possible view with the LED's blinding and tiring blue-light bouncing off the grind textures. I could pair it with the phone camera, but that sort of setup isn't conducive for quick and easy checks; you also don't want to be staring at anything for too long and too close with the LED source switched on.Mild edge-warping aside, the unit's magnification power is definitely better than my trusted Belomo (so the x30 power designation seems about right), but the overall durability of this type of thing is no comparison. Unlike the impressive, heavy-duty Belomo construction, this is Made in China in all ways, so you can't attach it to a daily-use keychain and expect it to remain functioning, or even there, shortly after, i.e., so not designed for field work. The LED light flickers and dims on occasion depending on how you grip the unit, but when you find a sweet spot, it works very well.So far, I've even utilized it in quick electronics' repair, so no buyer's remorse in the least, and a decent additional item to toss into any order, too, if it ever breaks.
