I too have used the Xantech sensors and can vouch that they are rock solid for installs.

The only thing to keep in mind (and this goes for pretty much all installs for cable connections) is to make sure the Xantech/Nevo wires will not be in the way of the maid or anyone around that area. I am speaking from experience because the maid knocked out connection from the sensor to the Xantech block and I had to drive there on a support call. When you add the Xantech piece, you are adding a power supply for the Xantech block, the sensor to the block and a two-wire back to the Nevo voltage sensor, so just make sure it's neatly tucked away and you should get perfect operation from this like I have. And yes, I tried this on TVs (using the current sensor module) and it works just fine.
