We have so far only looked at a couple of things in this microscope; a small flying bug placed on a slide, and a drop of blood (I cut myself doing some home improvement projects, so captured a drop on a slide). This microscope does a fine job of allowing us to view these things up very close. I‘m definitely glad I got this version with the fine-adjustment knob included rather than the less expensive version with only the coarse adjustment knobs.
The microscope itself feels solid and well-made. The 3-element rotating assembly works well and is nice and tight. The LED under-light works well with a nice smoothly adjustable brightness level. The stage is stable, with useful slide clips, and adjustable light aperture disc located underneath. This unit works equally well on battery power as with an AC adapter; for my purposes I'm sure we will only ever use it with batteries. The microscope also comes with a nice dust cover to protect it when not in use, and a secondary eyepiece to provide additional magnification when desired. At the highest magnification level with the more powerful eyepiece, the LED light does struggle to provide sufficient lighting, but you can still make out details on your subject slide well enough.

Honestly, at this price, I am quite happy with this purchase. I wish the LED light was capable of a bit more brightness, but for most purposes it works pretty well. The scope is sturdy and feels like it will last quite awhile. I also wish it had come with a better storage sleeve for the additional eyepiece. Even better still if the microscope had a place to store the extra eyepiece, or came with a storage case, but I'll make do. Overall, it should work great for showing my young daughter the interesting and amazing world of microscopic viewing.
