1 "Useless" Ms Palser 09 February 2021 I thought this would have a place for the stone to dip into so that the stone keeps part of the avocado fresh, i also thought the membrane would apply pressure to keep the half airtight. No, instead you have to remove the stone and the membrane applied the pressure of a leaf. It doesn’t keep it from going brown and you would get a fresher avocado if you put your avocado on a plate and wrapped some cling film over it, or used a silicone plate disk to apply pressure. Total waste of money. A note from the team Thank you for your review. We’re sorry to hear this hasn’t met your expectations and we’ve been in touch to offer a full refund.
