the product is perfect, and certainly works perfectly. It was sent to me super packed in a very short time. So nothing to say about the seller or amazon. So why THAN 3 stars? In fact, I wanted to measure the alcohol content of liqueurs that I make and that's the rub. Is made for measuring the alcohol content of a liquid by densitometry, ie based on the density. Or my liqueurs contain sugar, which greatly increases the density and significantly distorts the measurement! (Limoncello at 10 ° while it is closer to 40 ...) therefore unusable for sweet liqueurs. AC is only for the alcohol / water mixtures. I should have read the use of this BEFORE hydrometer.
