    Tiene una buena imagen, una adecuada iluminación, el costo y calidad son buenos. Llego antes de lo esperado.

    Para el uso que yo lo quiero esta bien el microscopio. Me llego con 3 filtros de diferentes colores, no traía aceite de inmersión, tiene buena iluminación pero he notado que en ocasiones se baja un poco la intensidad de luz. Al encenderlo y durante el uso se escucha como un zumbidito.
    La relación calidad-precio me parece justa.
    Los fabricantes nunca me contestaron para mi factura.

    En general y para uso personal, me parece una buena compra ya que cumple con el objetivo. Lo recomiendo siempre y cuando no sea para uso laboral intenso.

    Las fotografías que agregué son tomadas con el objetivo de 40X, 10X y 4X.

    I have a BSc in Bio/Zoo but have never actually worked in that field but retain fondest memories of my microscope work (Cell Biology, Microbiology, etc) including some summer-break field stints as a Limnology student. Still, my passion for Bio/Zoo has never really diminished. As I move into retirement, I wanted to pick up a scope to resume my interest in aquatic invertibrates. I looked at some great used scopes but chose this one because of its price and I free shipping (Canada). I have only had the scope for a couple of days but have already put in about 5-6 hours of observing (mostly old slides I made back in ’78, my own blood, and some pond water.) So far, I have REALLY ENJOYED this unit. Everything works as described. The objectives are achromatic but this is just fine for me, it was only really noticable when I was viewing some live Euglena at 1000X. The only concern I had is that the 100X objective is not marked “oil”…I have since confirmed with Amscope Customer Service that it is, in fact, an oil lens. I hope this is useful…I would buy this scope again.

    I have used various light microscopes in academic and research settings for 45 years. Now that I am retired, I needed a low cost microscope to quantitate parasite eggs in goat feces at about 100x magnification. A $55 toy microscope might work well enough for this but I did not think that I would be satisfied with that and I might want to examine animalcules at higher magnification for entertainment. The Amscope B490B microscope appears to be a good compromise for the factors of cost, optical quality, and mechanical stability for a microscope.

    Specifically, the packaging was secure, the components were clean, and microscope assembly was easy. There were no missing parts. It had a plastic dust cover, an extra illuminator bulb, a spare fuse, and some immersion oil.

    All components (coarse focus, fine focus, stage transit, objective turret rotation, etc., worked smoothly. The microscope body appears to be well built with fairly close tolerances (except, perhaps, for the slightly loose oculars).

    The microscope illuminator was centered and the illumination was intense (and adjustable). The objectives are reasonably parfocal. Image quality is good, especially for the price (compared to a $10 research grade light microscope system.

    The manual was written with some strange phrases and terms but the content was adequate for me.

    The attached image was recorded with an hand held iPhone from the B490B LM eyepiece.

    Excellent microscope, found my first tardigrades with it 🙂 I wish I had the trinocular version but it as a lot more expensive.

    I had bought my 6 year old daughter a toy microscope last Christmas. It was difficult to work with and not very satisfying. But, it did spark my daughter’s interest. So, I determined that I would get her a “real” microscope for her 7th birthday. I looked around on Amazon.com until I found this one. The other reviews indicated that not only was it a good product, but a good product for a child (some of the reviewers were home schoolers). We set it up on my daughter’s birthday, and it was clear as we unboxed it that this was a solid, quality, professional microscope. I had also bought a box of 100 prepared slides from Amazon so that there would be something to look at after we got the microscope set up. It really is a good microscope and I’m sure that it will follow my daughter through life as she grows up. Since then, I have also bought a slide making kit from Amazon so that my daughter can prepare her own slides. A side benefit is that my daughter’s uncle is a scientist, so he can show her the joys of microscopy even more than I can! I was also going to get a stereo microscope to serve as a bridge between the “real” world and the microscopic one, but my brother beat me to it!. I don’t have much experience with microscopes, but I did know as I was putting the microscope together out of the box that this was a solid, quality instrument.

    Received this earlier today and have been playing with it now for about 7 hours. I would note to others that there are several models of this particular scope on amazon that differ mainly in the accessories that come with them. As a side now, while not listed for this scope, it came with WF16x eyepieces as well as the 10x & 20x listed which was a nice bonus.
    All in all I am very happy with this purchase. The scope is heavy duty, and in watching youtube video’s from colleges to brush up on my scope skills, this scope functions the same as the olympus and other scopes they professors were using.

    Pros:
    *Mechanical stage is very solid and it’s easy to get around the slide and note locations with graduations. Single axis/dual knob control makes slide navigation and focusing at the same time easy.
    *3 eyepieces included giving additional 64/160/640 and 1600 magnifications.
    *Heavy construction
    *Halogen Illumination (I was told by several doctorate level researchers to avoid LED at all costs
    *Swiveling eyepieces
    *Includes small amount of immersion oil, extra bulb and extra fuse standard along with storage bottles for objectives.

    Cons:
    *While expected at this price range, there are some spots visible at high magnification in a couple of the eyepieces, but they in no way detract from viewing.

    Not a con, but I kinda wish I’d spent the extra bucks on a trinocular for camera/real time/tri person viewing etc. While you can get the adapter to attach a camera to the binoc version, if I was to repeat I’d go ahead and get the trinoc version.
