VEVOR Trinocular Compound Microscope, 40X-5000X Magnification, Digital Laboratory Trinocular Compound LED Microscope Two-Layer Mechanical Stage Computer Connection for Students and Laboratory

- The head of the microscope may come loose if frequently moved but its easy to re-tighten with the provided side screw.- There was a bit of dust on the inside of the lens pieces but it was easy to wash off with methanol. I'm sure other cleaning solvents like Xylene would work just as well.- The included instructions kind of assume that the buyer already knows how to use a microscope but a quick YouTube video can easily train you to use it.+ It was unclear in the pictures if the 100x objective was an immersion objective so I was prepared to order a 100x/OIL objective. Thankfully this product's 100x objective can be used with immersion oil.+ The 40 and 100x objectives are slightly dimmer than the microscopes I've used in my lab but the sample is still easily viewable at max brightness.+ The resolution at 2500x is good. At 5000x, the resolution is still surprisingly good. If you know how to properly focus a microscope you will easily be able to see individual cells, nuclei, and bacteria.Some reviews complained about the resolution with the 100x objective but it is important to note that immersion oil is needed at such high magnification; I don't see any real problems with the high magnification that Vevor advertises. I bought this microscope to stain and view bacteria out-of-lab and encountered no issues after about 3 weeks of use. This is an incredibly good and relatively cheap microscope for home experiments and beginner to intermediate labs.

Bought this for Christmas for the kids. It’s amazing but could use a little more instructions on using it. The phone older is not for your average cell phone size either.

NO CAMERA USB

How do I order a new one?

I also purchased this microscope as an Intermediate scientist. I'm so disappointed the camera didn't even come in mine. Also, Everything was contaminated even the inside of the lenses had hard-to-remove bacteria. I needed to bring out the bleach for the freaking microscope lenses! I just put the darn thing away to clean when I had more time and gloves. It's so gross. How do you even get bacteria inside a lens that not even alcohol would remove?

I bought this for a club in school and the kids were so excited for its arriving. But I was disappointed by the quality of this product: the camera does not justify the description, the images it shows were blurry even after multiple adjustments by a professional. Well, now we will have to wait again for a new one to arrive.

The image is unclear, the lights flicker, and why are the glass pieces broken? I can't find the instructions at all and I can't use it.

Was missing thumb screw. Came in broken.Did not come with pc camara.
