I was playing with the X1 blasters the other day. First I disconnected the blaster and used only the hub, all worked in my configuration. Then I connected the external double blaster to the hub, placed the double blasters exactly where the hub was, and moved the hub back a bit and covered it so it's internal blasters were not involved. Basically, it didn't work, way less power than the hub, definitely should not be called 'blasters' at all. I went black to a properly located hub and it's fine.

In these 'update available' posts, please mention the version number we should expect, so we can make sure I have the latest.
