I tried these the other night for the first time. They are very filling and I did them in the Actifry (without any fat as not necessary).
As I said they are very filling and very fa/thick , but for me they are nothing special - certainly better and less fuss than SW-style chips, but not a patch on the Actifry chips.
Morrisons have them for £1 for 1kg too. Be careful not to have them on an original day, as I had to change plans mid-day lol.
