Alot of love has been put into this design and the software that goes with it.The software has a USB-C PD protocol analyzer that shows you the communication between devices as they negotiate the voltage and current levels that will be allowed and supplied which is very helpful if your designing a device that had USB-PD sink or source features which is what I'm doing which is something I have not seen in a device at this price range. This was a pleasant surprise when I started looking into the software features.The firmware is easily updatable via the software also which means you will not be missing out on any new features as the USB protocol changes over time.The display has a very nice layout and is easy to read and and navigation of the features is alright once you get used to what buttons do what.It's surprisingly smaller than I expected which makes it easy to bring along if you want.For me this allows me to quickly verify the power output of battery banks, AC chargers, and the power consumption of devices I use or am testing. The software allows you to graph out everything over time and save it to a file for later use or comparison.I can tell a lot of love was put into this design, UI, and Software and feel like for $100 it's a steal if you can use all the extra features it provides.Chargerlab has a great Blog where they tear down power banks and bigger solar charger systems and show exactly what is inside and what chips were used if your into those types of things. They use this meter to verify the capabilities of all these different products which means they have to make sure the meter is capable of detecting all the latest USB PD and other standards which means this will always be getting updates as things change over time.I would say spend the extra money and buy this one if you want the best.
