We have a brand new Philips Avent ISIS iQ Breat Pump with all the kit. This was a replacement after the one we had broke, but by the time we got it, it was no longer needed. The stuff is completely un-used and even includes a new style colic reducing bottle as a replacement for the old one as we had pinched the existing one from the packaging at one point.
It's the fancy one that mimcs a rhythm etc seen here
Cost ~£90 new and still does. Yours for £50
pictures to follow...of the pump not it's application.
