Works really well, however be aware that these devices will flood your network with Multicast traffic. If you are using a basic unmanaged network switch or even the ethernet ports on common Internet routers (such as Telstra Gateway) then you'll likely experience significant slow down/congestion in you network performance.
This is by design, not a fault of the HDbitT. To remedy this make sure that you use network switch(es) with IGMP snooping. This ensures Multicast traffic is not sent to hosts that have no need for it. Alternatively you will need to have these devices on a separate physical network or use a VLAN (most switches supporting VLANs will support IGMP snooping anyway).
