I think they are perfect bottles and I used them with my daughter and with my son. But currently, I changed to an other brand, because they have 3 different teats and MAM has many more and they want u to change the teats in every 2nd months which is expensive.
Be aware, sometimes it is cheaper to order from MUM's website than from the biggest online retailers website. Even there is a delivery charge.
The prices are ok.. Not the most expensive bottles and u can use them again, just need to get the plastic seal and teats to the bottles.
They used to give free bottles. I think they do it with one of the big pharmacies now. It is hard to find vouchers.
I never asked for refund, because the products are nice.
The delivery came in time.
Customer service is nice, if u have any question, they answer to you.
Do I recommend the bottles? Good quality, but in long term u spend more on them than on the other brands. Something we all think about when we have babies and we need to buy so many things.
