Quality item, still cheap
Although quite tricky in calibrating, the refractometer does its job very well. Well built, with a sturdy body and a variable dioptry ocular, it is delivered in a very protecting plastic & foam box, together with a mini-screw for calibration and a long transparent rubber dropper. The reduced measurement range makes reading the measurement results extremely easy. Well worth the money!
