Product meets all our expectations :) Sturdy construction and good clear views with a decent wide-field of view. Bought a mechanical stage for the product after the purchase.... with higher powers, moving the slide manually is troublesome. Also purchased some prepared slides and blank slides (blank slides are a must). Opened up a new world for my son... he's very pleased.

The same version of this microscope is also sold with a 10x (read 10-power) and 15x eyepiece. By multiplying the power of the eyepiece by the power of the objective lens, the 10x eyepiece when used with the 4x, 10x, 40x and 100x object lenses produces viewing powers of 40, 100, 400 and 400; respectively. The 15x eyepiece produces viewing powers of 60, 150, 600 and 1,500. However, the 100x objective lens is an oil immersion lens and while it produces outstanding views, its might be a little advanced or inconvenient for the casual viewer. Oil immersion (the oil is provided with the package) requires a drop of oil to be placed between the objective lens and the item you are viewing; thus, you are looking through the oil while viewing. The 400 and 1,500 power views with the before-mentioned competing package requires oil immersion leaving non-oil immersed viewing powers of 40, 60, 100, 150, 400 and 600.

Generally, most casual viewers will work do most of their work with lower powers (bugs, pond ameoba and the like) and having a 600 power view is more than adequate for viewing blood cells and many types of bacteria.

This microscope package provides 10x and 25x eyepieces providing non-oil immersion viewing powers of 40, 100, 250, 400 and 1,000. Using the 25x eyepiece, an effective viewing power of 1,000 can be obtained without using oil immersion, which is superior when viewing smaller bacterias. Oil immersion viewing is not difficult, it's just that its a little messy and will require an objective lens clean-up after using. Most casual viewers will not have the patience... it takes a bit of concentration when focusing to keep the oil between the specimen and objective lens.

If you so desire, you can always purchase a 15x eyepiece separately (about $30). My son and I perhaps do most of our viewing using the lower powers (40 to 400). We are also using a 32mm focal length wide-angle "telescope" eyepiece with the microscope, which produces about 30 power when using the 4x objective. This lower power is better for viewing stamps, coins, etc. Fortunately, the "telescope" eyepiece fits nicely around the outside of the microscope barrel (telescope and microscope eyepieces have different diameter barrels).

The added plus for this package is the camera, which is a nice addition for still shots and video. The camera has an effective microscope eyepiece power of 16.

With the additional of the mechanical stage (about $19), this is a complete setup and there are no cons or complaints regarding this package. You'll need to get some stain (about $6) for bacteria viewing. Go to youtube for examples of how to make stained specimen slides.

For our purposes, I think the eyepiece selection in this package is superior overall for the casual viewer. The setup will serve my son well while in junior high school through college. I'm very impressed with the quality of the AmScope microscope given the price.

I suppose one can't really expect anything spectacular for $180, although according to the marketing ploy it's price is $900 which is totally absurd for something of such average quality. Worst thing is the teeny little screw which holds the eyepiece housing. It is situated on the underside of the housing tube and has a very short thread' so after half a turn it fell out and bounced away never to been seen again unless you have a smart floor cleaning robot with microscopic vision. Lacking the screw, it is almost impossible to get the camera to stay put or even the right way up.

Bought this for my son who loves science. This is a great microscope so far! My son is amazed! The USB digital camera adapter makes this even more amazing. *** I would recommend this product *** but be forwarned 1) the directions are not for new users (Youtube was a great help!) 2)to change the ocular lens requires a tiny philips head screwdriver like that in an eyeglass repair kit , not included and 3)the higher magnification uses immersion oil which requires lens wipes for cleaning, not included . Overall, seems like a well built, easy to use microscope.

Honest reviews on AmScope 40X-2500X Advanced Biology Science Student Compound

I believe this microscope may be for teens and older students, but I ordered two of these microscopes as gifts for families with young children, three are age seven, in Puerto Rico and Florida. Last year, I decided to spend my money on true educational "toys" instead of computer games or other ridiculously expensive gadgets for kids. The two scopes went to my siblings, grandparents who spend a lot of time with their grandkids and who would hopefully put them to good use. I also sent them a lab manual and several Golden Book nature books. The microscopes have proven to be such a hit with most of the family, namely three generations who have been collecting leaves and all manner of specimens to view with the children, photograph, and upload to the computers. One seven-year-old is using it to do his school's science presentation. I'm so delighted with their enthusiasm that I'm ordering a third scope for a family in Virginia that home schools there four children who range in age from two to ten. Spring will soon be here and it's the perfect time to enjoy and learn about their environment. By the way, if I had more time, I would love this science tool for myself.

Well I couldn't believe the capabilities of this thing. I came down with Lymes Symptoms & I hate to say, Morgellons, just recently. I already knew how everything was going to go at the dermatologist and the doctor's. It went just like I knew it would except I actually passed the Elisa test instead of just flunking it & the Western Blot tests for Lymes Disease. So, disgusted with my doctor's ignorance and not listening to anything I had told her, I got a sample of my blood, looked for the bacteria, and found it. That was the easy part. The other things have been tough to try and sort out. Why am doing this instead of going to another doctor, yet. Because I know all too well if you don't already have a cookie cutter problem they will miss and miss and miss. Several years ago they missed my metastatic breast cancer tumor that was the size of a walnut that you could see for three months. Because at that time I didnt fit the criteria. That criteria no longer exists. I looked into my symptoms, lump, lymphnodes and knew what to do and knew it had spread since my neck nodes were swollen. That surgeon who I requested a biopsy from said to me, "oh, your chances of having breast cancer is like being hit by lighting." I just told him I still want the biopsy. I couldnt believe he was so ignorant? Well, anyways, doctors don't have time for you. Find out all you can about your situation before you go in for any appointment. And good for you if you can take some classes in microbiology or anything useful ;)
