Product Cons

• Limited Accuracy and Functionality: Only assesses battery status simply via voltage; cannot accurately detect battery capacity or performance under load. Functionality is basic compared to professional digital testers, potentially leading to misjudgment.
• Quality Control Risks: Some user feedback mentions receiving a product where one unit was non-functional, indicating potential issues with batch quality stability or quality control.
• Difficulty Aligning for Testing: Some users report difficulty aligning or securing the battery during testing, impacting the user experience and efficiency, potentially less stable than competitors with integrated designs.
• Long-Term Reliability Concerns: Mixed customer reviews regarding "accuracy" suggest that its precision and reading consistency over the long term may not match that of higher-end competitors.
