Very very good. The others I have from the most well-known company come off much more easily. These ones from mam fit very well and stay on for a good amount of time. If you have a strong milk flow, then it might come off more easily but not always, while with the other brand in this case they come off immediately. Overall, I started using them because one of the twins went to the hospital and got used to the bottle, so they helped us get back to breastfeeding. I would definitely buy them again.

The shape is quite convenient. The only problem is that it easily comes off after a few uses. However, I have also bought other very famous ones that had double the price and those, due to their shape, did not fit at all and came off from the beginning. So, in relation to their price, they are very good as compared to the more expensive ones, I was much more satisfied. I would definitely buy them again

They are very helpful when there are wounds. However, one should not breastfeed constantly with the protectors because milk production decreases.

I tried many because my baby, due to prematurity, couldn't latch onto the breast and had learned to feed from a bottle in the NICU. These were the only ones that worked in terms of size, and with them, we were able to establish breastfeeding!

Very good with a slightly harder surface in the nipple area so that it bites you and you don't die of pain.. They fit perfectly!
