I got my Luxura pens yesterday.

First impressions they are a lot better design than the Ergos. The case they
come in looks like a leather glasses case with a velvety type material
inside. The pen themselves look a lot more stylist than the ergos. The
cartridge holder is now a screw type and is of a similar design as the
Novopen. When th cartridge is inserted into the holder the end sits slighty
out of the holder (this is to press the locking ring inside the main body to
allow the plunger to move). On the pen I have the cartridge holder seems a
bit tight when screwing it onto the main body (it feels as if it's cross
threading but I've unscrewed it to make sure and it isn't).
The dial-up is exactly the same as the ergo but feels more comfortable when
pressing down.

I'll try and get some pictures uploaded as I can't seem to find any (as yet)
on the net.
