I just had a new set of Miele Ultraphase 1 and 2 cartridges delivered and they're now in the new format packs with the neater looking design and foil top, but the scent has also changed.
I'd argue it's a lot nicer as I found the original one had an OK scent, but it had a somewhat bitter undertone. This one smells more like classic detergents - just that very subtle and mild scent of fresh linen.
