The Diamond Tester Pen with Portable Diamond Selector has garnered a mixed response from users. Many customers appreciate the handheld design that fits conveniently into bags, making it an excellent tool for on-the-go jewelry assessments. The high accuracy of the tester has been highlighted as a significant advantage, with several users expressing satisfaction with its performance and value for money. One user even suggested that a YouTube tutorial could enhance the understanding of how to operate the tool effectively, indicating there is a learning curve involved. However, not all feedback has been positive. Some users encountered issues with the device's accuracy, experiencing frustration with its inability to Consistently detect diamonds. The magnifying glasses included with the tester also drew some criticism; the focusing distance is deemed inadequate for examining hallmarks, which diminishes their practical utility. Furthermore, users reported that the light feature on the diamond selector was unreliable, requiring frequent readjustment, which can hinder the testing process. In summary, while the Diamond Tester Pen has aspects that users find beneficial, such as portability and effective performance for some, it also has notable shortcomings that have disappointed others regarding functionality and usability. **
