Do not get the s12! They are rubbish! The motors stop working and then the company claim to refund you 100% but only give 50% and a breast pump ( I got double.) Then that will break and stop working so it will take you weeks to get them to sort it, they will send another double pump this time by which time your supply is gone so you gift it to a 1st time preemie mum and it doesn’t work so you contact them, they don’t read emails properly, they ignore you, they don’t answer your questions and then tell you you’re unreasonable while then telling you from last Tuesday to wait 3-5 working days for a full refund only for it to get to the last day and them tell you that they haven’t done it. They then block you from their page because you posted it there and then still not tell you when you’ll get the money back.
