Underlay for laminate flooring on concrete

Blueruby

In need of some advice please. I have bought some Wickes Arreton Grey laminate flooring for my hallway and dining/playroom. The subfloor is concrete and fairly even. Wondering which underlay to buy as an confused with the range available in the stores.
Saw this one from Selco vapour-barrier-foam-underlay-15m
Will this be suitable for my purpose?
Saw this on Ebay Comfort Gold 5mm - Acoustic Underlay For Wood or Laminate Flooring sold by flooringdirect08, is this any good at all?
(Sorry, unable to post links. )
If neither are suitable, kindly suggest which ones to buy please.
Awaiting your input. Thanks.

The underlay I like has both good sound and insulation properties, also some moisture resistence, too. Much easier to use than fibre board, which is easily damaged and dusty to work with.

I would have this lay on the concrete first, though.
