Review: Saved my pumping journey - Has saved my pumping journey. After using a rival wearable brand for the first 4 weeks, which slowly stopped working for me as elastic nipples were getting more painful, I knew I had to switch pumps to something that suits elastic nipples better. Because this has a longer tunnel, I don't have the issues I had with my old pump, there was a small flange sizing kit inside my box (but reading other reviews, some people didn't get this previously) and I'm no longer in pain pumping and my supply is gradually increasing again to keep up with the demands of my twins. It's bulky, and takes attention to put on properly , and the suction is STRONG so I keep my settings very low. Also recommend using coconut oil on the flange to reduce friction/pain. I'm a fan of the larger cups too, for me the capacity is enough and better than my old pump which I'd have to sometimes empty before continuing the pump session. Love the fact I'm not worrying about charging it several times a day too.

## Questions & Answers

**Q: What is DL or SL stand for please?**
A: Dl= double 
Sl = single.
Don't know what the l stands for, maybe lip? 
However all it means is the cup thing that goes on your breast is double or single flanged (the rim that secures it onto the pump)

**Q: Hi. Does anyone know if this would fit an S9 please? I cant find a set for just the S9.**
A: Hi I have both the s9  and pro
The cups are different in size pro is smaller

**Q: What is the difference between SL overall and DL overall**
A: DL is supposed to have better suction and generally better performance as well as holding the milk more securely.

**Q: I need 24mm flange, so what do I buy?**
A: Looks like this has a 24mm flange already.

Money well spent! I really needed an additional pump on the go for when I’m not using my Spectra. I did a lot of research and ended up going with this one. Best choice ever, I get almost the same amount out as my hospital grade pump with the convenience of being able to move around and do things at the same time. To make sure it works well it needs to be set up properly and you need to get the right flange size (which is not included in the package but you can get various sizes on here for very cheap. I know the price might be an investment but in my opinion you won’t regret it.
