Bottle question!!

I've been using the Avent natural bottles but recently tried the Playtex drop in bottle. I really like the Playtex because they are so much easier and faster to clean.

I'm debating buying a bottle warmer (currently just running it under hot water, but it takes too long when baby is hysterical). Could I use a bottle warmer with the Playtex drop ins? Any recommendations?

Thanks!!
