### ⭐⭐⭐⭐ Just what I was looking for
*by H***1 on November 22, 2024*

I was looking for an illuminated loupe for knife sharpening. I have several standard loupes that I've been using with a flashlight to light up my edge. This does pretty much exactly what I want plus the lens is a lot larger than my Nikon 10x loupe so I can see more of the edge plus the handle keeps my hand further away from a sharp knife blade. The scale for me is not really a necessity, it is a little strange their website shows it has 0.5mm as well as 1/32" scale but these units only have metric. So it that is a deal breaker i would reach out to Engineer maybe they still carry the dual measurement units? Few reasons I gave it 4 stars and not 5. 1. No case or lens caps so you may end up with a scratched or dusty lens if you leave it out. 2. I did not look at Engineer's website before purchasing but the picture is difficult to gauge the size of this unit but it is a lot larger than I was expecting. It uses 2x C batteries so the handle is big. I was hoping for a smaller unit to put in the case with my knife sharpener. 3. Build quality is not the best (but hey what do you expect for less than 30 dollars). The unit feels like its made of cheap flimsy plastic. With the batteries inserted it rattle around like a cheap 2 dollar flashlight. The optics are about on par of a sub 30 dollar unit. There is chromatic aberration, center has the least but as you look further out it gets worse (you can see it on the scale). It's good enough for what I need it for though. I will probably invest in some AA to C battery adapters, I think the choice for C batteries was overkill for a single LED light source.
