Review on Nenesupply 9Oz Wide Mouth Feeding And Storage Bottle Compatible With Spectra S2, S1, And 9 Plus Pumps - Includes Nipple, Sealing Disc, And Compatible With Spectra S2 Accessories And Pump Parts by David Berry

I got the Spectra S2 pump from my insurance to replace the Medela PISA that I had been using previously. And of course, the bottles have different size necks! I was discouraged at how expensive additional bottles were, until I stumbled upon these bottles. They are considerably cheaper than the Avent bottles that also fit. They are sturdy and I've had no problems with the text fading (however, I do handwash the bottles, so I cannot vouch for how well they stay when using the dishwasher). The only thing I have not been the happiest about have been the lids--even when I've had the lids on all the way, I have had them leak on occasion. I am careful to not tip the bottles over, so I haven't experienced that often, but I think that it is something that NeneSupply will need to address at some point.ETA: I have been using these regularly now for over 6 months, and I must say, the quality of the product is still quite good. The text has not faded and they work well for pumping. The only thing I don't like is that they don't always stay tightly screwed onto the flanges for pumping, but I think that may be a function of the fact that it's not deep threading; the bottles that came with the pump stay on slightly better but also come loose as well. So I am not going to take any stars off for that. I have also dishwashed these on occasion and had no problems with them being on the top rack. I still typically handwash but that is because I need them more frequently than we run the dishwasher.
