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.

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.

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.

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