Iittala Tools cookware - anyone with experience using this ?

I just stumbled upon these pans and pots from Iittala called ‘Tools’

I think they used to be made by Hackmann, but are now under the Finnish brand Iittala.

They have a smashingly good looking design, seems very sturdy and have excellent handles and lids.
Only minus is the lack of a pouring lip.

Well there could be another minus - I have no clue of how well they perform ?
I think it’s clad/ply but not sure if there’s also a copper layer inside.

As far as I remember the old Hackmann pots had a thin copper layer in between the aluminium and stainless steel layers.
Not sure if this cookware line still has this thin copper layer.

Anyone with experience or knowledge of this cookware line ?
