blibloWearable Breast Pump Milk Collector Cup Accessories, Compatible with NaNaLazy/Nonlet Wearable Breast Pump Compatible, Milk Collector Cup(1 Count Whole Bowl)

These are a foggy white. Not clear. I haven’t decided if I’m returning them or going to try them, but I don’t like that they are not what was pictured in the advertising.Update: I tried a set and they don’t work. They are much more stiff than the normal valves and membranes. I pumped for an hour and got less than half of my normal supplies. I put my only worn valves back on and got more out! Just don’t purchase these.

I have purchased several valve/diaphragm replacement sets from other sellers for my Momcozy S12. I have never had any complaints. However, listen to the reviews on this brand.#1. The picture of the item depicts a clear, standard-looking valve set. However, the actual item is a cloudy, powdery-feeling silicone.#2. The silicone is of low-quality. It is a very soft silicone, with a diaphragm that barely fits on the motor housing hole. The result is poor seal and, therefore, poor suction.#3. The duckbill valves are also very soft silicone, and they arrived compressed in a box. After taking them out, I realized there was a space in one of the valves, which makes it useless for suction and vacuum.#4. This item is apparently "unavailable for return," which is ridiculous. I bought 2 other sets, and both of them from other sellers could be returned (I checked out of curiosity). I had to contact Amazon directly to request help with this item. Any seller that does not provide return policies is an automatic red flag.I suggest running from this item, if you are trying to buy the valve/diaphragm set.

I have the MomCozy S12s and these fit perfectly. I’ve noticed better production since I switched to these newer replacements so they do the trick! Way cheaper than buying direct from MomCozy

Do not buy this product! First of all I was unaware of the no return policy on this item or I wouldn’t have taken a chance. I’m a struggling single mother who needed new pump parts to fit my Momcozy S9 and tried to save money. DONT! The Bliblo parts are way different than the original Momcozy parts in every way. The silicone part is thicker and I didn’t think anything of it until I tried to put it back together after taking it apart and it was not easy, it was even hard to see which part was together and which weren’t just had to feel for it. Then the motor DID NOT FIT! As you can see in the first picture there’s space in between the motor and the plastic bowl with Bliblo and in the second picture is the Momcozy brand even after I just used it and it fits snugly onto the bowl. I did not even try to use the Bliblo overall being that the motor did not fit all the way on! I have no extra money and I can’t return this so I’m trying to warn others. DO NOT WASTE YOUR MONEY!

Let me start of by saying I purchased two of these. Product claims to fit S12 pumps…we’ll one does and one doesn’t. I don’t even understand how that could happen other than the fact that there must be a quality control issue. The one that works, works great. It is a bit trickier to put together than the ones that came with my pump, but not impossible.So basically if you can afford the gamble of either getting one that works, or one that doesn’t, than go for it. If not, I’d steer away because these cannot be returned.I also should clarify in how the one does not work. I am able to piece it together just fine. The problem lies in the top. For some reason the motor is unable to flush into the carrier like it is on the other (and my original). If I force downwards pressure onto the motor, it slides into its where it should be, but then immediately pops back out.I hope this makes sense. Maybe I just happened to get a dud as the other one works.Rated due to the fact that I can’t promise someone if they ordered this, that it would work. I will update my review if somehow anything changes.
