The Breastmilk Collection Bottles compatible with Spectra have been a great addition to my pumping routine. They fit perfectly with my Spectra pump, are easy to clean, and the measurement markings are clear and accurate. The bottles are durable and provide a leak-proof seal, making them convenient for storing and transporting milk. Highly recommend for any Spectra pump user!

These are perfect for my Spectra s2. I got them because I needed bottles for my morning pump when I get 8+ oz in each breast which is too much for the bottles that spectra comes with. These are perfect. They fit my flanges perfectly and hold a little over 9 oz. I was skeptical about the lid being totally sealed and not leaking but it actually works very well and the lids are compatible with my 9 oz Avent bottles so I use those on the go and the bottles always lay sideways and never leak with these lids! the measurements are also easy to read on the bottles. Love it!

These are a great cheaper alternative for storing milk. The cap has two parts, so it is a bit annoying to wash

These bottles will fit any large ring lids/nipples (avent is what I use) and compatible with spectra/motif and other wide mouth pumps! I love that they hold so much milk and the erasable tops are convenient to write the date, we all know that we always forget even when we say we won’t!

These bottles are made from a very thick plastic. The numbers and tick marks on the side of the bottle are raised plastic instead of ink. It’s difficult to see inside the bottle due to the material thickness and color - the plastic is much more white than clear. They are very sturdy and fit the Spectra pump flanges. The rubber lid caps can be removed and replaced with a nipple. The Lansinoh or Pigeon nipples fit well. Overall a good value and works as hoped with my pump flanges and the bottle nipples that I use.

Very happy with these bottles. If you're looking at this you probably already know why you'd want larger bottles (you pump more than 5-6 oz per side at a time and overflow the bottles that came with your pump, and/or you single-pump and don't want to have to empty the bottle in between sides, etc.). These are great for those purposes. Fits the standard wide-mouth threading of, for example, the Spectra S2. Sometimes they don't lock on to the flange and I recommend a small piece of masking tape across flange to bottle to prevent the bottle twisting off when that happens (or for backup; I just do it all the time so I don't have to think about it). Not enough to ding a star for in my book.The volume markings are accurate and include 0.5 oz increments starting at 2 oz (also 10 mL increments starting at 60 ml). The markings are very persistent. There is no sign of any degradation in the printing after a couple weeks of daily washing. (Compare this to the collection bottles which came with my spectra pump; the ink came off completely within a week or two).The lids are great. They seal well. When assembled they function as one piece (unlike the fiddly plastic disk you use with many bottle rings), and they pop apart easily for cleaning. I haven't written on them.Update 4/9/17 (over a month later):I stopped using the tape as the bottles started locking securely to the flanges again (not sure why). The volume markings are still perfect after about two months of daily use/washing. Great purchase.Update 6/5/17Bottles still look new and no trouble with the bottles staying attached to the flanges in the past two months. 5 stars all the way!Update 6/19/19, with pictureI used these for almost 10 months, and while the marks did eventually degrade some, all were still readable. I’ve now used them another month or two. The markings are well-worn but mostly useable (see picture). Aside from that, the bottles are completely functional and I’m considering getting a second set.

The bottle does not screw tightly onto Maymon or Spectra pump flanges. I had to carefully hold the bottle to prevent it from falling off during pumping.Plus, the volume scale on the bottle appears to be inaccurate. 120 ml measured in a Dr Browns bottle translates to approximately 124 ml in this bottle.
