YOCTOSUN Head Mount Magnifier with 2 Led Professional Jeweler's Loupe Light Bracket and Headband are Interchangeable

(English is not my first language, so please excuse the writing) I am an Illustrator and I bought this product to help me with a handmade graphic novel which Im working in. I need to trace with ink, then paint with watercolor very small details. Right when I began the project and my eyes were very tired after finishing 2 or 3 pages. Then I began to use a hand magnifier, but then my hand became tired as well. Therefore I tried with the Yoktosun head magnifier. The detail and precision that can be achieved is amazing, and the adjustable position of the light and the lens is very useful. however after long use (2-3 hours) which is my case my eyes were very very tired, even more than when I was not using any magnifier. I don't know if that is something about my eyes, or something about the magnifier lens, I used mostly the 1.5X and the 1.0X lens. I also use the product for reading and even for watching youtube on my cell phone, which is very funny because there is a lot of details that pop up. For short periods of time is excellent but not so sure for long periods. I also had a little trouble with one of the lens but received a superb customer service from Yoktosun to solve it. PROS Superb customer service Light product (However, if you are not used to a product like this, like was my case, and plan to use it for long periods of time, like me, expect some kind of initial neck pain or stress in the back of your head while you get used to it) The look and feel of the product is excellent, the box with the lens is also very practical, and even elegant. Variety of lens. CONS Not sure about what happen to ones eyes when the products is used for long periods of time.

If you're an electronics enthusiast or pro, I highly recommend getting this to make working with smaller components a comfortable experience. I'm pretty darn happy with this product. The head sizing is a bit on the narrow side for me, but I have a pretty wide head. The only thing I would say is a true negative is that it's designed to take 3x AAA batteries if you want to use the LED illuminator, which makes this too front-heavy in my opinion. The lenses are high quality - unlike cheap magnifies that have lenses with obvious warp and distortion, I could not perceive any uneveness when viewing through these lenses. At higher magnification, there is some chromatic aberration (unavoidable - you can't cheat physics). If they were somehow able to offer an achromatic set, I would be willing to pay lots more for this. But for the price? These are fantastic. I am kicking myself for not buying these years ago! The lens position is easily adjusted, and the lens "float" in front of you with plenty of unlenses open space around them so that you can, for example, have a magnified view of your workpiece and then glance outside of that field for a normal view. This work well for me for doing SMD electronics assembly work. As I'm getting older, I can't do SMD work without magnification. With these magnifiers, I can see 0603 components and pads at a comfortable distance and then peek out to my schematic, BOM, and the labels on the component bags, all without having to touch the magnifier. 2.5X and 3.0X seems to work best for me. Keep in mind that higher magnifications have a shorter focal length, so there are some tradeoffs that you'll have to experiment with. When I was younger and didn't need anything to work on 0603's, I probably could have worked with 0402's all day long wearing these.

I bought these for the interchangeable magnification. I build models, paint miniatures, and do small-scale products such as electronic soldering or cleaning the sensors on my various cameras. These all require different levels of magnification for me, so I decided to give this set a shot. First, what I'm comparing this to: I have one of those old school visor-type magnifiers. You know what I'm talking about. And I only have one power for it. I can purchase more, but that was a separate cost and this new set was more economical than the same levels of magnification bought separately for my old unit. Out of the box, I was impressed by the build quality. This unit was way more sturdy than I was expecting for the price. However, that is also its one potential downfall. With the batteries inserted and with the weight of the full power lens, this becomes quite a hefty piece to be sitting on the bridge of your nose for an extended period. The head strap does alleviate the pressure a bit, but it's still very noticeable. It remains to be seen how comfortable these will be for a longer painting session. (It's worth noting that you can slightly adjust the nose bridge, if you're careful, by bending the arms in or out for a better fit -- and this also helps with comfort.) The LED is surprisingly powerful. However, the cold, flat light makes me think that this will be more useful for projects that only require light, not quality light (such as electronics). For painting, I might just stick with my normal lamps. Now it's the lenses in this kit that really blew me away. Optically, they are phenomenal! In a direct comparison to my old magnifying visor, it's like night and day in terms of clarity. The lenses in my old visor are clean and scratch-free, and they seemed fine. But after looking through these lenses, it's like I'm looking through fog with my old set. I was truly and honestly impressed with these lenses and this is far and away the best part of this kit. I feel like this will be nearly perfect for my needs. If necessary, I'll update this review once I've had some longer sessions with it.
