Good quality

Fit with my medela swing, no issues.

They’re not identical to the original parts, the color is the slightest bit different. But they work just as well and are a much better value!

Good, durable, true to standard replacement parts.

There's not much to be said. The parts fit perfectly on my Medela brand bottles, in fact, the valves fit slightly better. They are snug, but pop off easier for washing. The thickness of this brand of valves and flanges are similar to the name brand, with negligible differences such as color.I will update on the longevity of these pieces in time. I have currently pumped with greater success since changing my original brand valves and flanges that were wearing out. They lasted me me two months as an exclusive pumper, before one valve cracked due to the struggle of getting it off, and the others barely stayed on.

Bought these to replace my spectra ones and they work great but are a little tight.

I kept losing the pieces to my Mendela hand pump. This item is great as it comes with multiple pieces, as I will/have misplaced the white pieces.

Only thing that sucks about hand pumps is the cramps you get after pumping.
