Liked that they came pre-shaped however, within a couple of days one patch has come away so will need to replace with another.

Patches would not adhere to Pertex material, despite the area being thoroughly cleaned with an alcohol wipe and allowed to fully dry. I have repaired multiple down and synthetic jackets before and never had this problem.

Sadly no good. Tried three different patches. All came off in a few hours.
