Good Seller lower the price of the product for purchase. the Good: Very big screen of 1.8 inches show a lot of information. Very Good quality of storage case for the tester. Very easy to use MultiKey to navigate the settings. You also PC program. More options for test USB cable resistance. support a lot of charging protocols. the Bad: it has no PD convert from USB-A port. Overall highly recommended seller and company.
