Thin silicone? No. It's twice the thickness of the Medela and so much more bulky. It falls off due to the shape if the flange, unlike the Medela which stays put. Honestly if I had tried these first I would have thought all nipple shields were awful. But no. It's just the Avent ones. Get the Medela ones, most people are medium. Don't waste your money on this pathetic attempt of a product.

I used these shields on and off for the first weeks of breast feeding as we all go through cracked nipples and tenderness they were great but just a tad slippery once the milk flow gets going i found my daughter would latch and she would suck them right off

These drive me crazy with falling off & make breast feeding stressful (but i need to use them due to flat nipples)... Worth spending more on other brands which stay on a lot better (but still aren't great). Seems they lose their suction within a few uses.

Bubs and I had thrush my nipples got so cracked I nearly gave up feeding. I persisted for 9 wks before i was given this shield by my mchn I used to cry when he latched on now I am pain free and feeding is more comfortable. My don easily latched on with it on
Comfortable small easy storage
Easily lost due to clear colour

I am a first time mum and within a couple days of bub learning to feed my nipple become cracked and made feeding him unbearable. Using the shield allowed me to continue breast feeding pain free while my nipple also had the chance to heal while using them. They would stay in place, not leak and not slide off. I still cringed when he would first latch but it was for no reason as there was zero pain anymore and within a week of using the shield I was able to breast feed again without them.
Painfree, stayed in place, inexpensive, able to continue breast feeding, allowed nipple to heal within days.
Need to be a little persistent getting bub to latch on as they r a different size and texture to the nipple.

My 2 month old boy would constantly cry if I tried to Breast feed and would only take breast milk if I expressed and bottle fed. This upset me, so I decided to try nipple shields, as they may feel similar to the bottles teets. He took to them straight away, and it felt as if he was breast feeding like normal. He didn't cry at all! I suppose if u were looking for a nipple shield to be exactly like a nipple these aren't it, but nothing will ever be exactly like a nipple. They worked for me because it was bigger then a nipple and he could attach easier. They saved me!!
Cheap, flexible where it needs to be, works
If you have a big let down the nipple area can fill up with milk and therefore can get messy

I had to use these for the two months that I breastfed. My sins latch was fine but he hated breatsfeeding!
I tried all other brands but the holes in others were too small and my son hates that he couldn't get milk out fast enough.
These things were a life saver for me!!
Fast flow, gave this mummy heaps of relief
It fell off easily if my son wasn't feeding straight away.

These nipple protectors are a handy little product to have around if you are having any issues breastfeeding baby. They are very portable and come in a good container. Quite cost effective as they do last a while. But can be a bit fiddly and are easily lost.
Easy to find this product in chemists and department stores selling baby products. They last for a while if you look after them. Not too expensive, usually sold in double packs. Very easy to use once you work them out.
Sometimes it is very easy to lose them and you can be forever looking for that nipple protector.

As another reviewer posted, there can be issues with saliva/milk getting in behind the shield and affect the seal, causing them to slip, but I found just removing them and giving my breast and the back of the shield a quick wipe was easy and made them stick again. Because of the good amount of contact you get between baby and breast, they're less likely to affect your milk supply than some other brands that have the shield covering the entire nipple area. Using these shields my daughter and I had our attachment issues sorted out within a week, and no cracked or sore nipples!
Easy to use, soft, mouldable silicon, easy to find and relatively cheap, good contact between babies chin and your breast
can get a little leaky

they were great to use, when I first started breast feeding & I was very sore with cracked nipples, these protectors helped me & my baby heaps. Main problem was milk would get behind the shield then it would fall off. After giving it a quick wash, it would go on again fine. These shields were a life saver. I would recommend these to other new mums if you have some nipple pain. if it mean you can continue to breast feed it all worth it.
very comfortable to wear
like others have mention, milk builds up behind them & then they fall off.

As soon as any liquid gets near these shields, milk or saliva, they just slide everywhere. The first time I used these my bub squirmed and the shield slid right off and into his mouth. He started spluttering and I frantically pulled it out. It scared me so much! Even though I was trying to hold it in place it just kept sliding everywhere which frustrated by hungry bub. I tried at another feed, giving them the benefit of the doubt, but the same thing happened. I will never use them again.
Price was cheaper than others.
They CONSTANTLY slip off!

Tried to use these when I had cracked and sore nipples from first time feeding and they weren't of any use. The nipple part on the shield seemed too hard for my son to be able to get good suction so it didn't work for me.

Did not allow my son to latch on so did not work for me.

They were a waste of money for us, I could not get them to stay in place long enough to have bub latch on correctly. He would get frustreated with all the mucking around. I didn't end up using them as it was just to hard in the end.
Like all Avent products you can find them in most stores
I couldn't get them to stay in place and baby could not latch on.

I thought Id go with some Avent shields as I have an IQ pump and IQ warmer thet have both been FANTASTIC. Additionally I was told to buy some sillicone shields. So with little time to spend shopping around due to a new baby... I sent out the poor husband to get some.... MISTAKE. Waste of money. Have a rubber Pigeon one that is a MILLION times better.

Perhaps im doing something wrong with them, however there are no concise instructions on the packet or the website. Another poor effort on Avents Behalf
Nothing. They dont work
GARBAGE. Dont waste your money.
