The media could not be loaded. My total satisfaction with the microscope's packing was reflected in my reaction when it came. Each component was well protected, and the directions for putting it together and using it were presented in a clear and concise manner. It took me around fifteen to twenty minutes to get the microscope ready for use, and the procedure of setting it up was straightforward. In my opinion, the first impression was pretty favorable since it seemed to be well-constructed and long-lasting, which is particularly noteworthy when taking into consideration the cost. When it comes to binocular eyepieces, the eyepieces were pleasant to use, and the adjustment knobs moved smoothly, which is usually a positive indicator that the construction is of high quality. Using the higher magnification settings, I was able to view plant cells, onion peel, and even certain germs in a clear and distinct manner. Generally speaking, I believe that the optical quality is satisfactory, since the pictures are clear and crisp even when seen at lower magnifications. On the other hand, when I progressed to various greater magnification settings, I noticed that the clarity began to decrease somewhat. When it comes to microscopes in this price range, this is not something that comes as a complete surprise; yet, it is something that you should be aware of if you are trying to get precisely crisp pictures at every level.

I have been using this microscope quite a bit since I purchased it a couple of weeks ago. For students or kids this is a fine tool, but for someone who has used quality lab equipment, it is lacking. For example, the rotating eyepiece spins freely and no matter how tight you turn the set screw, it continues to move out of place far too easily. For the price, the optics are clear and the overall body of the scope is sturdy, but the plastic control knobs feel cheap and the directions are worthless. It will do the job, but it is not the quality I had hoped for.I should have spent a little more to get a higher quality tool for adults.

It has a good focal range of 40xto2500x and the images are sharp and crystal clear, I also like the refractive index has a wide adjustable range so your not having to squint all the time to see the image. This is a good quality microscope that’s capable of real, practical use .

My kids always use their phones after school,so I bought them a microscope as a toy.I want them to get an early start in science and develop an interest in the natural world around them.The microscope is quite sturdy, with two eyepieces and four objective lenses.It even came with ten prepared slides, which look very clear. For 100x magnification, we’ll need cedar oil, but we haven't tried that yet.They're very interested, and in a few days, I'll let them make their own slides.

I bought this to use at home for fun. I'm a biology major, and this microscope is nearly the same quality as the ones we use in our labs.Pros:The price is very reasonable.Includes 10 prepared slides, 50 blank sides, and 100 slip covers.Metal construction.Includes foam-lined case for travel/storage.Has 4 objective lenses.Pretty good optics.Cons:The prepared slides are...okay overall. A few are good, a few are meh.The 25x oculars blur the image.Stupid USB power cable that is too short.Single light source.A pitiful amount of oil is included (the picture is accurate).Additional thoughts:Many manufacturers include higher-power ocular lenses to market a higher magnification power. Adding a higher power ocular is similar to zooming in on a picture you took with your phone: you'll get a closer look, but since it doesn't increase resolution it appears blurry the more you zoom. 1000x total magnification is the upper limit due to the wavelength of light. To achieve a clear 1000x magnification with this microscope, you need to use the 10x ocular and 100x objective, with a drop of immersion oil on both the top of the slide cover and the lens itself. If you don't use oil, you will get a blurry image due to how light refracts through the air. The oil fills the air gap between the slide and lens which provides a clearer image.

I bought this microscope for a small home project. I have a biophysics background. I worked for a company that sold microscope for laboratory research 20 years ago To my surprise, the image quality of this microscope is very close to the lab microscope that cost five times more. The focusing mechanism and the stage moment are very smooth. The lens has a very flat viewing field. The simple photo bracket with a smart phone holder worked better than the traditional trinocular microscope, and eyepiece camera. The image is fairly sharp. This package comes with everything you need to get a good microscope image and photo. It contains a set of prepared biological sample, glass, slides, cover, glass,immersion oil, smart phone holding clamp.There are several things need to be improved. 1) Parfocality is not very good. When changing the magnification, user has to refocusing the microscope. But the problem is mostly on the low magnification range, especially for the 4X objective. 2) poor instructions. For people who has not used microscope before, the included instruction won’t provide much help. There is also a bottle of liquid with no label. based on the color, I thought it could be a lubricant oil, but it turned out to be the immersion oil.Attached the pictures were taken by this microscope with a iPhone 13 camera. They are from the red blood cells samples slide included in the package.
