Anyone using a LAN isolator?

Just bought an Acoustic Revive RL1-1GB-Triple C Lan Isolator.

@jerrybj where did you buy the AR RL1-1GB and can I ask how much?

I kind of am but only for lightning protection at the cable modem / wifi router junction.

Keep in mind that Ethernet is inherently balanced and galvanically isolated. There's no metal to metal path thanks to the use of ICs with built in isolation (not sure about PoE).  

Wish USB was like this.

If you wanted to try this, use this:

From Ebay US$225.

There have been faint murmurs of copies, but there seems less chatter on this product.

Where do I place my LAN Isolator?

Options are:

Between ethernet wall socket and modded network switch

Or from network switch to streamer.
