AmScope M150 Series Portable LED Monocular Student Compound Microscope - 40X-1000X Magnification - Microscope Kit Includes Dust Cover, 2 Clips & 2 Eyepieces

Great Value BuyYou will be very pleased after buying this microscope, as it is an extremely good option, especially for the price. The ideal user would be an infrequent user that doesn't not require an extremely high quality internal look inside cells. I personally use this microscope for analyzing semen samples collected from swine. I am fully able to accurately assess motility and morphology of the cells.How It Can Help YouThis microscope will allow you to accurately view cells on a molecular level. If you are looking for a basic entry level microscope I am quite certain that this device will more than exceed your level of expectations. The criteria I used to evaluate this product are pretty basic; ease of use, quality of focus, and light permeability. You will find that this product is extremely to use. The basic setup of the focus knobs are easy to distinguish between the corse adjustment, larger knob, and fine adjustment, small knob, easily allowing you to finely adjust your viewpoint on your desired specimen. I also appreciate the quality of focus this device can provide its users, which after purchase I'm sure you will too. Lastly the adjustable bulb shade allows you to effectively shade the amount of light that penetrates the slide. This will allow you to easily push light through darker specimens or lower for clear cells.Closing The DealOverall, I would highly recommend this product to nearly any entry level user it can come with a few draw backs for a more advanced user such as, inability to see inside cells clearly and lack of a binocular objective, which could be expected as it is clearly marketed as a monocular objective however I do think it could improve the ease and clarity of use. However, this scope has fully met and exceeded all of my expectations for this device and I am extremely happy with this product and would buy it again.

Viewing ability is great. Easy to use. Brightness is great, focus is good. Slide quality is great. It is great microscope for beginners, not to cheap but not top of the line. Quality of what you use in high school. Good weight to it. Would order again

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.

While not super sophisticated, this works great. I read other reviews and had some concerns thinking I might have to return this, but I'm quite satisfied with the functionality given the price point.I added the provided 3x AA batteries, flicked on the power (light worked great), found a spec of wood fiber and just put it on a slide (which I had bought separately for a few bucks), clipped the slide in, and it was immediately in focus (which was a happy accident). The zoom in/out controls worked well - tight enough to feel solid, but loose enough to turn without much effort.When switching to higher magnification, I had to turn the brightness up which was easy with the adjustment knob.I should have gotten a scope with controls for a sliding table/shelf because at these scales moving the slide is very sensitive. But I got what I needed with this.I would suggest this for a beginner (like me) who is in need of seeing tiny things :)If I have longevity issues with this, I'll update this review; but for now, it has done exactly what I needed.
