Using an adapter to get a quick in/out to your system is one of the benefits of Dante, as this can be done without having to run XLR cables, and without having to find spare XLR outputs. Such adapter aren't cheap (welcome to Dante) but the Tight AV adapters represent quite a saving over other products.
OK - the XLRs are not Neutrik (you could swap them out) and the RJ45 connector is not Ethercon - but the same is true of other, more expensive adapters. The initial setup is a breeze: I use static IP addresses and still got two of these things configured in less than five minutes. After that, you just plug it in, it pops up on your network, and you're good to go.
Remember, it's PoE so you can't use it without a switch, and it's primary network only: so not good for mission critical connections.
A great product and relatively inexpensive.
