Stride 5 oz Breast Pump Cups - Dishwasher Safe, Food Grade Silicone, BPA Free - Accessories for Breastmilk Storage & Pumps - 2 Pack

Works great. Has a much better seal than the one that arrived with my pump. The stopper also is more secure.

The only reason why I had to buy these front parts of my pump was because the pour spout of my ordinal pump broke and there’s no replacement.

I only bought these for the piece at the top, which is the only part of the pump that isn't sold separately and is the only part of the pump that has broken after a year plus and 2 kids' worth of pumping. Otherwise, I love the elvie pump! It helped me produce so much more than with my previous kids.

I bought the Elvie stride breast pump and accidentally lost one of the stoppers and they are not sold separately, I had to buy the complete set of cups and also there are no compatible brands of these pieces only Elvie brand.

I am stuck with this product since I ordered the elvie stride pump through my insurance and decided to order an additional part to keep a spare one just in case. After only a month and a half of using it every other day since I had an additional set both parts of the cup started to leak. milk while pumping. I research online and it is quite a common issue after a while and because of heat (for example: sterilizing it at high temperatures) the seal starts to bend, warp, and or expand and that is were the milk starts to leak. They do have a 90 day warranty either way proof of purchase but unfortunately they do not sell the seal as a stand alone product if you are out of the warranty period you will have to but the entire set again, not worth it.
