Doesn't stay sealed
Easy to use, however, air 'leaks' in and so does water if using for sous vide

Thanks for your feedback Nerida, these bags should create an airtight seal, it isn't common for air to get in once sealed. I would try using the clip the close your bag and double-check that it is fully sealed before using the Vacuum Sealer. Make sure you don't overfill the bags as this can affect how well it seals (I have made this mistake before). Hopefully that helps, if not you are welcome to get in touch with our customer service team and they will be able to help.
