Review on 🍸 ATC Alcohol Refractometer for Accurate Spirit Alcohol Volume Percent Measurement, Wide Range 0-80% v/v with Temperature Compensation by Andrew Dickens

I've never been so disappointed with an online purchase as I am now! I bought this tool to use on a small project I have. The moment I received it, I immediately opened it and followed the collaboration instructions that came in the box. When I got to the step where I need to screw in the screw, I found some wear on the screw (shown in the image uploaded) meaning it has been used before. I kept going because I really need a tool but the screw just won't turn. I've used everything on it and it still won't spin. The reading was out of range and needed to be calibrated, but that can't happen as the screw isn't turning. The tool requires high precision, so I can't let it open and rotate. Very disappointed!
