Review on 🏌️ State-of-the-Art Golf Cart/Deep Cycle Battery Rapid Hydrometer Tester: Optimize Performance and Maximize Battery Efficiency by Jason Holt

Bubbles stick to the electrolyte indicator too easily, especially on the "backside" of the "arrows". This is despite the idea of keeping the block level when the electrolyte is sucked in (to avoid bubbles). Despite my attempts to be smarter than the designers' mistakes, from time to time the bubbles will push the indicator higher than it should be showing. In other cases, the bubbles will clog the indicator and it will not float at all. Or it gets stuck somewhere along the way. About 25% of the time, swiping your finger across the device helps. Cleaning and refilling helps maybe another 25% of the time. It should be a simple operation that does not require such mental gymnastics.
