Bottle warmer recommendations

Ftm, due in March. I'm planning to bf, but my baby's father and I don't live together, so I'm looking for a bottle warmer for when the baby is with him. My question is, is there a particular warmer that works well for different bottle brands? Since I'm not sure what the baby will take to the best, I planned to get a few different bottle brands. However, I've noticed that every brand of bottle has their own specific warmer, as they come in so many different shapes, so I'm not sure what the best option would be. Any suggestions?
