The brightness is excellent. So far I have good focus with the 4x, 10x & 40x lenses. I am waiting for my immersion oil to come before I can review the 100x lens. I am using this microscope for the study of lactobacillus, acetobacter and yeasts.

I comes with a very good carrying and protective case and 3 pair of eyepieces: 10x, 16x and 25x. I wasn't expecting to get all 3 pairs so that was pleasing. The body of the microscope is metal which is also pleasing vs. cheap plastic.

It comes with slides and covers which is nice not to have to make an additional purchase for those items. It does not come with any prepared slides in case you wanted some.

The LED screen does lose clarity through transmission, but perhaps that is to be expected with all microscope screen adapters and cameras for this price range <?> I don't have experience with other microscope still-shot and/or video cameras to know.

I gave only 4 stars for beginner friendliness, because if you aren't familiar with microscopes, the instructions aren't the greatest. However, you can watch the video on their page or do a YouTube search for this brand of microscope, they do have assembly instructions instruction videos which are helpful.
