comfortable and Pain-Free
I bought a full kit before, but it was really hard to fit and not very comfortable, so I decided to try this flange instead. Honestly, the quality is even better than the original one. The edges are smooth, the size fits perfectly, and most importantly, it’s comfortable to use. I don’t feel any pain at all. Plus, it’s HSA eligible, which is a nice bonus. really happy :)

Worth the buy
I wasn’t sure if it was worth buying a whole new flange and just keep using the removable sizing inserts. With two less things to clean, I would say pumping is less stressful. I use this with the Spectra bottles. Just be sure they are on tight! I had one incident where the bottle knocked out with a bunch of breastmilk, but I haven’t had any issues since.

Durable
I’ve had these for a couple months now at least and they’re still holding up really well!

Works! But Beware
It gets the job done. Just keep in mind it doesn’t necessarily fasten tight. They unscrew fairly easily luckily I haven’t had any milk spill but it has come loose several times you just gotta pay attention. I’d recommend getting inserts instead, little more annoying but you don’t run the risk of it unscrewing and spilling everywhere.

Perfect for Spectra S1!
I measured 13 mm on one side and 14 mm on the other, and the 15mm flanges work perfectly! No pain, and good value.

Not very good quality.
Flimsy with rough edges.

No valves
Good quality flange, fits spectra perfectly but no valves despite clearly staying flanges + valves. Disappointing as now I'll have to order more.

I’ll be honest, at first I didn’t really like these flanges. I think it was just because they felt different to the usual flange I was used to, especially with the insert, so I wasn’t sure about them at first. I decided to give them another go though and honestly, they were actually really good! I’m not even sure why I didn’t like them the first time 😂 Once I tried them again, I found they worked really well and I had no issues. They fit my Spectra perfectly and are really handy if you’re looking for compatible flanges. Sometimes you just need to give something a second chance! Overall, I’m really happy with them. They work great with my Spectra and I’d definitely recommend them.

Bought these to replace my broken Spectra flange
Bought these to replace my broken Spectra flange. It works ok, not the same as the original parts. It loosens from the bottle when in use and doesn't stay on properly when pumping.
