Excellent component tester – Highly recommended for electronics technicians! I purchased this Awgem TO2 Series component tester from Banggood,and I am very impressed with the quality. The build feels solid,it is easy to use,and it correctly identified my MOC3011 optocoupler with a green pass indication. The test sockets are well designed,making it quick to check optocouplers,transistors,MOSFETs,diodes,LEDs,and many other components. As a biomedical equipment repair technician,I troubleshoot PCBs regularly,and this tool will save me a lot of time compared to checking every component with a multimeter. Pros: Accurate and fast testing; Good build quality; USB-C rechargeable; Compact and portable; Excellent value for money. Packaging was good,and the product arrived in perfect condition. Very satisfied with this purchase. Thanks,Banggood!
