The attached images are 40 x (10x4), 100x (25x4), 250x (25x10) and 5000X (25x40) of a leave, respectively.
I use some high-end microscopes in my work and didn‘t expect much for this “toy". Well, it turns out to be a surprise. The image quality is not bad for general use, and I'll suggest don't use the 40x objective for thick samples like a leave which will be very dark. (but still good for a very thin layer of onion).

I hope it can come with a couple of glass slides so that I can mount samples on it and I'd like to pay a few more $s for it. I have to use a plastic plate at this moment.

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.

This is not a professional microscope but it is above a toy .If you want to take a quick look at lower magnification it works great. The highest magnification is useless . Can never achieve focus at highest magnification . The subject will hit the lens and never be in focus. For what it is and being all metal and the price I like it.

This is a sturdy, accurate microscope. The resolution is very good. The light is bright, too.

It has been easy to operate

I bought this on a prime day special. We are using it with my high schooler‘s Apologia Biology class and it is working just fine. I was concerned that a less expensive microscope wouldn't be as good for the Apologia biology class, as they recommend a different, more expensive brand. But, we couldn't afford the other one and this one is working out great! Definitely consider this one if you are looking for a good homeschool microscope and don't have a lot of money to spend.

Feels fairly heavy and sturdy in the hand. Neck has plenty of space to accommodate your hand when you pick it up. Nothing feels loose. Magnifications work simply and easily. Knobs are pretty solid and move smoothly. NOTHING on this microscope feels too cheap or flimsy- everything feels like good quality materials. Great purchase because of its quality versus its price. I can‘t compare it to more expensive versions since I've never purchased another at a higher price, but it definitely beats the ones I used in high school (which while heavy were finicky and frustrating to get a clear picture from). I'm sure my teenage son will continue to enjoy it for a long while.

Good on a budget microscope.

Love it so far! Dont forget to buy some slides. Great clear image once you get used to how to use it and its focus.

Price to power this microscope is awesome! It came with an information sheet and a pamphlet with a web site and QR code link to the manual. However, the provided info details the controls, operation and trouble shooting just fine. In fact, about the only thing the manual has that is extra to that is a lot of technical specs that I personally did not need. Which I knew before the product arrived because I took the time to look for it. If you HAVE to have a manual, all you have to do is google the brand and model for a manual and like magic, you have it right there on your screen to read and/or download. I had ample time, between ordering and the arrival of the product, to watch videos and research to re-familiarize myself with basic operations, functions and practices of microscopy so that when my order arrived, I was looking at my red and white blood cells in minutes! I can hardly wait to go to our local duck pond to get water samples to view. This is an awesome microscope for the money.
