The parcel arrived in Samara in 14 days. I believe that the TKDMR tester is the best in its class. Smooth increase in current, unlike other, cheaper testers. The voltage drop on the working led gradually increases to 2.8 volts. I order a second time. The first device worked for 3 years. Thank you to the seller. I recommend the product for purchase.
Works fine. LED display is blue, for better contrast I preferred red.
