Perfect - Works EXCELLENTLY and is FLEXIBLE with the multiple ports! It has MANY screens with many details and not just one that the advertisement image shows

Positive: it does what it promises, the measurements. I have tried even a 25-watt device, it works great.

Small and easy to use with sufficient interfaces and a fairly readable screen. I can't confirm the accuracy of its measurements, but empirically they seem correct. It is certainly a tool for amateur use, and I don't think anyone can have expectations (nor need) for third decimal accuracy unless they are a network technician.

It is a quite useful gadget, especially in cases of USB devices that you are not sure if they are working or if the laptop port is the issue. Its price is a bit high, but it has many features that someone may find quite useful. Among its advantages is the ability to connect USB-C.

Very useful. Works as promised. The Bluetooth function is a very important addition as it records changes in voltage and current over time as a graphical representation.
