Review on 🏌️ MiLESEEY Professional Golf Rangefinder 660 Yards with Slope Compensation, ±0.55yd Accuracy, Fast Flagpole Lock, 6X Magnification, Distance/Angle/Speed Measurement for Golf and Hunting by John Huskisson

Saw this in December and ordered the size I needed and easy to use. Of course it was in a case and was kept until March and I used it 1 time before Covid 19 struck, then the course reopened in April and I used it 4 times and realized I thought it was rope or what's on the lens. and cleaned it but it wouldn't go away so i asked one of my golfers to look at it and they said it had a crack and now liquid seems to be floating in it. I thought I bought a warranty but can't find any information about it. I sent someone an email regarding this, but no reply. I need help
