Review: The UM25C USB tester with colour LCD and Bluetooth

The Elektor department for tools, equipment, kits also contains some really useful articles: Some of my more recent articles include the DVB-T USB sticks as DAB radio and QI chargers for smartphones (which will be appearing shortly) and for these I used a plug in USB tester to take measurements of USB voltage and current drawn by the USB devices. I am now however in possession of a similar but much more capable measurement device. What additional features does this neat bit of test gear offer?
