Even though it doesn't seem as sturdy as the one I had in the past it works just as good. Arrived calibrated and seems to be holding so far. Plus it's all black haha.

Was pretty much calibrated when I got it, corrected a tiny bit and works great

Cons: I have a portable charger so its a plus for me. If you don't have a portable charger, it will be hard because it needs light, which they provide and you just have to plug into the charger to used the light to see.|Pros: The product is great, easy to used, easy to clean,you just need to get used to, I give it a couple try and it was easy.

This product works just as good as any expensive brand refractometer but for less money very accurate as well

I bought this because of the reviews that claim that it is easy to read and calibrate. I found that this is not the case. I have to hold this thing about 4 inches from a 100 watt lightbulb just to begin to make out the numbers. It's a lot like trying to focus a cheap pair of binoculars. It does work, once you can see it, but that's the whole trick. Also I wear glasses, confounding the issue even more. I would not recommend this product.
