[QUOTE=britbronco22;14489297]I normally use IRIS, but particuarlly at T5 it doesn't seem to be any quicker than using the normal EU line.
There always seems to be just one machine working, or someone in the line that tries to use one booth for ages even though they aren't registered.

Maybe I'm just unlucky, but my experience has always been that there have been lots of people who aren't registered in the queue ahead of me frequently resulting in the standard EU line being quicker than the IRIS one. I quite like using it though!
