As others have said, I wouldn't pay for a faulty hub replacement, even to get a newer model. Either get retentions to send one out for free or just get a fault replacement. There's no guarantee you'll get a like-for-like replacement, nor is there a guarantee you'll get a newer model. It depends on what the fault tech has in his van that day, or what they have at the distribution centre when they post one out. However, you're not out of pocket due to it.

Instead of forking out £20 on another VM hub, I would suggest you spend a bit more and get yourself your own wireless router. It's much better in the end and means if your hub conks out, the replacement isn't going to wipe your network settings.
