Graphing single or both channels simultaneously allows you to see, understand and compare waveforms, signal spikes or signal dropouts without needing to spend extra time setting up a major equipment saving you time and money
With a voltmeter per channel you can use Amp Clamps/shunts and Transducers (Pressure, temp, etc...) to see relationships in real time and how they interact. i.e. Amperage and Voltage Draw at the battery or component shows you its health.
The N2 is the first step in a series of products, mobile applications and integrations aimed at giving you more insights to what you are looking at.
I've used it extensively in debugging auto electrical problems. My old car had a poor crimp on a battery terminal - it would charge fine for the first few minutes and then slowly stop charging as the connection warmed up... could show this by measuring voltage and cable drop over time as I drove.

First the good: A totally unique and useful device. All the normal features of a multimeter, in a very small wireless package. Very low power consumption, so low that it is not worth turning off (and no way to, other than a shipping mode). Time will tell, but it is supposed to last a year in standby. Perfect when it is difficult to use standard meter, things that are moving etc...

Two readings can be shown in a real time graph, perfect when making the connection but can't look at a reading at the same. A buffered burst mode and very high sampling rate allows transients to be observed that normally would require a scope. The two readings can also be shown plotted against each other for power factor etc...
