Bottle warmers?

My hope is to ebf this baby (I’m due September 6th) but I bought 1 can of formula and some bottles just in case it doesn’t work out.

Who uses or plans on using a bottle warmer?

I just purchased MAM bottles and now I’m wondering if I should get a bottle warmer as well, but I am not sure which one to get🤨

These are the bottles I’ve bought.
