At first I was undecided whether I should buy this USB meter, but have given me the recessions others think. Because it good price I have but then decided it ... ... And no regrets. The device measures in my opinion precisely, at least prove the comparative test with another multimeter. It is easy to handle, so it hardly makes it work to use. And I sit there a often. The only way I could make very interesting discoveries in my charging cables smartphones and eliminate sources of error.
Overall, I can only recommend this device for fast and easy measurement of USB connections.
