Yes, we've got an X4 (after recommendation by several ABer's). Does the best vacuum of any cleaner we've had before and has a longer than normal handle, which is good as we are both quite tall, so you don't get back ache. Only thing I've got against it is that the tools hose isn't as long as, say, a Hoover, so its a bit tricky doing the stairs (takes 2 of you!). John Lewis are the only shop who do them (for about �250), but have a 'google' and look for direct delivery. We got ours for �201 delivered.
