I received the Z5 and appears to have better receive sensitive and error correction then X5 on weak channels.The channel edit freezes up and channel move does not work. internal power supply has been removed. Will not accept channel map from X5 so need to scan channels new. The 2 amp 12v power supply has a European connector so replaced with different power supply with US connector as I do not like adapter supplied.
The power connector needs to be glued to case as 1 hard push will break it.
The performance of receiver is good and fast channel switching. Internet function works ok
