I purchased this item 5-6 years ago. I use it once a year at harvest to take test samples from machine harvested grapes and it is accurate to within 0.1 Brix on each batch tested. Bringing a crop to market that requires certain sugar standards is a very valuable tool that more than pays for itself after one season. Yes, I would highly recommend this product, it is extremely accurate compared to more expensive commercial digital refractometers.
