Are they medium flow ?

Not sure what the package had said but they are definitely not slow. I'd say medium but if you want it to go faster, I unscrew the lid a millimeter, like a crack and it flows faster so you can slow it down if you want to put it on tighter. It's just my kiddo like to gulp it down!~ I LOVE these bottles and the nipples don't crack like rubber ones. I went back for a second pack so I had extras.

Yes, they are medium flow as best as I can tell. There is only one hole in the silicone nipple, but the flow is such that it will drip milk if the bottle is held upside-down. I started using these when my baby was around 4 months old and she had no problem with them.

They come with a #2 nipple. Which is a medium flow. But you can purchase slow and fast nipple.

My slow flow has 2 mentioned but it has a "S" mentioned which I believe means slow flow. We recently changed to a medium flow and it says size 2 but "M" Mentioned on it

So sorry for the late reply. I would say they are medium, but on the soft side of that.

I would be suspect if there was a noticeable flow difference. My experience has been that new filter cartridges produces a better flow for a while and gradually diminishes.

Hi, Judy. They are smooth. But, they are plenty thick enough to do the job.

These came with the medium flow nipples. I too, had expected the fast (what I wanted)

No...it's a steady flow, nonadjustable...but it is nice :) I like it a lot!

They are more light to medium. Depends on how hard you work out. What I like is that I can do deep water exercises hands free as these also give buoyancy in the water.

No they seem to be very smooth and consistent. Very nice mugs. However, If you are looking for something a bit heavier, these may not be the mugs for you.

No, I can feel no flow restriction. Typical supply lines from shutoffs to sinks are 1/4" as well, and most sinks have plenty of flow.

It's medium flow (but not terribly fast). Side note: I found it extremely difficult to find the slow flow nipple replacements.

I believe they came with the medium flow. Our son uses fast flows, and I recall having to buy them for all the bottles after purchasing this set. You can get another set of nipples for around $5 I think.

Yes, they are. I love them. I got them last year and everybody that comes to my house want to take them from me. Just one little advice: don't fill them up too much, because then it is hard to pump. :)

The one on mine had medium and slow flow. The small bottles had slow and the big ones had medium.

Medium I think. Good transition speed from bottle nipples. Doesn't leak fast if tipped on side

I would think they are. Definitely straight and smooth, not like the free ones from the paint store. Life is grand!
