I ordered 4 sets of ice crampons from them, but they didn't ship within the window and the order was cancelled. Have now received a PM from the vendor telling me that AliX made a mistake and the items did ship, so could I now pay them! In other words my CC was never debited.
However as that order cancelled I went ahead and bought them elsewhere (eBay) so not inclined to pay twice.
I guess if they sent me a pre-paid envelope I could send them back?
This is what I ordered from AlixX: (knock-off)

and this is what I ordered from eBay (genuine)
