Cooling Rolling Pin 3 "Ergonomically Poor" Mr Troop 13 August 2019 I've been looking for something like this for years and was really excited to try it out. The features on it are brilliant and really handy, and the quality isn't bad, but the way some aspects have been executed is really quite poor. The stopper that opens to add ice/water on one side is made of soft silicone, and is therefore almost impossible to open as the groove isn't big enough to pull on and twist at the same time without it bending. I still can't get it open! It'll have even less grip if your hands are covered in oil from pastry or water from icing, which almost defeats the object. A note from the team We're sorry the stopper has proved difficult to remove.
