Review on 🍷 Chefast Triple-Scale Hydrometer Combo Set for Wine, Beer, Mead, Kombucha - Alcohol Hydrometer with Cleaning Cloth and Storage Bag - ABV, Brix, and Gravity Tester - Home Brewing Supplies by Chuck Hernandez

Instructions for use for this product are limited. However, the detailed e-book instructions link sent with this product is broken and not working. I contacted the seller but never received a reply. This defeats the purpose of using a hydrometer when calibration is disabled and I have no way of calibrating it. Seller, if you are reading this please send me a link to the e-book. UPDATED 6/8/2020: After a 2 star rating and another attempt to contact the seller for hydrometer instructions, they emailed me the hydrometer calibration documents. areometer. I give it a 4 because of the hassle I had to go through to get instructions as the hydrometer arrived uncalibrated.
