    Высочайшее качествоReview by Максим
    Отличная лупа производства легендарного БелОМО. Очень понравилась. Красивое фиолетовое просветление. Увеличение очень сильное и без потери качества. Оптика просто великолепная. Качество изготовления без нареканий. Удобная, надежная (металлический корпус), продуманная конструкция. Настоятельно рекомендую. (Posted on 12/25/2018)
    Happy!Review by Khank
    I’ve already got a Belomo 10x magnifier, which is, by the way, a high-quality product, which served me well for many years. However, now my requirements have changed and I need a loupe with higher powered magnification. That’s why I ordered 20x quadruplet magnifier with Belomostore. The product came in time, and was just like I supposed it to be. Now, the magnification was absolutely satisfactory for me. However, everybody should keep in mind that as magnification strength increases, the magnifier becomes harder to use due to a smaller field of view. All in all, Belomo 20x loupe made me happy once again.
    Thanks to the seller for quick response and delivery! (Posted on 12/25/2015)
    Far exceeded my expectationsReview by Nick Slave
    Got the Belomo 20x magnifier 2 months ago. Since that it has become an everyday tool for the work. Fortunately, it provides sufficient magnification for all of my tasks. It was my principal requirement for that kind of optics. Although it needs more light in dimly-lighted room.
    Far exceeded my expectations. Yes, I would recommend it to my friends.

    Incredible!Review by Alex M
    My new BelOMO 20x magnifier is something incredible. It’s extremely accurate and powerful, so that I can see every detail in clear and concise fashion. The lens itself is of a very high quality. 20x magnifier has steel round swing-away case. Although it is made of steel, it is lightweight. I also believe the loupe to be durable.
    I consider BelOMO 20x to be one of the best lens' on the market for that price. I’m pleased with this purchase. Very good value!

    Good magnifier especially for that moneyReview by Eithan William
    Ordered 20x BelOMO loupe together with the branded lanyard. So, the device is always with me at work. The loupe is well built and compact. For sure, optic has bright and clear view, lens produces close and undistorted image. Be ready to examine the object by single parts, as you need to hold loupe close to your face and to the object under study. For my work, in fact, it’s more of an advantage. Overall, good magnifier especially for that money. (Posted on 6/10/2015)

So, loupe makes correctly its work. (Posted on 5/31/2015)

    I already have one loupe ordered with Aliexpress. Being fully dissatisfied with that Chinese plastic loupe of low quality, I started searching for a new one. Actually, I was moved by the price. It was something like 10$. But then I changed my mind for the sake of a real bargain. Finally, I chose BelOMO 20x loupe. The product is good, and the focus is well. For certain it's the right thing for my job. Really good value for money. Thanks. Recommended. (Posted on 5/28/2015)

    A reliable loupeReview by Stephanie
    One of my friends advised me to buy BelOMO quadruplet 20x. I was surprised because earlier I had never heard about such a producer. But afterwards I was surprised even more since I got a very high quality loupe and its price was really good. What I like about my loupe is that is made of metal which is nice to the touch, the images that I can see through this quadruplet are bright and clear, it is not heavy. Thus I can recommend BelOMO 20x to those who want to get a reliable, high-quality and rather cheap loupe. (Posted on 2/24/2015)
