can you warm these bottles in the microwave?

Warming up milk in the microwave is not just dangerous because of heat pockets. It is also the case that it changes the structure of the milk, so it is not as good or natural for your baby anymore. Don't consider microwaving any milk!

Will these bottles work with a Spectra S2 pump?

I have the 4oz bottles and the Spectra pump S1. You will need an adapter (https://smile.amazon.com/gp/product/B01A4LUZA4) to attach to the Spectra since these are narrow mouth bottles. I've found the combination works well with the adapter but be warned that the 4oz bottles are heavy so, depending on your use case, the 9oz ones could easily be too heavy to use with a pump.

Do you guys use these for breastmilk storage as well? wondering if i need to get both. if so, i'd like to get reusable storage bottles/bags.

I don't use them to store breastmilk because it would be to costly. But they can be frozen so if you are freezing the milk it will work. We v only have two bottles so I use the medela storage bottles when pumping and storing milk. I wish life factory sold glass bottles without sleeves for storage.

What's the best bottle brush to use for these bottles that have a very small opening?

I use the Norwex bottle brush. It's rubber so it is easy to keep clean and maintains its shape. Have used mine for 10 months and it's still fine.
