arrived this morning - my PS3, BT Vision, PC & Mac - works perfectly.
very easy to install. to avoid irritating blinking lights, make sure you place it far from your desktop, Mine is sitting beside the Hub. and my hub is approximately 5+ meters away from every computer in the house.
Excellent little Switch. I bought this as I needed wired ethernet access for 4 Laptops with only 1 network connection. Easy to use - just plug all the cables in and away you go.
In response to some questions I have seen from other reviewes for this product: This Switch does not replace a router - it will simply increase the number of connections available from a router.
