Anyone used Remi Cachet mini tips?

Merry Christmas Geeks!

Remi Cachet claim their mini tips return to their original shape and don't need retipping to be refitted. Has anyone tried them? What's your opinion?

TIA x

They say they're made with German keratin. Just wondered if anyone has used these or has used German keratin for retipping?
