Bottle warmer recommendations?

So I bought the momcozy warmer. But TBH - I don’t use it. When I was giving breast milk, it was always either fresh or room temp (if given within 4 hours you don’t need to refrigerate). Now my babe is on by heart powdered formula and I use room temp baby water. He doesn’t mind room temp and sometimes even likes it cold.

We used the tommee tippee warmer (with MAM bottles), never had any issues with colic however it takes ages to heat the bottles

We have the tommee tippee one, but it takes so long to warm up, that I stopped using it after a couple of days. It was quicker to boil the kettle and sit the bottle in a jug of boiling water until up to temp.

my sons formula was the only one that didn’t work in the baby brezza machine so the entire thing was just a bottle warmer.. but highly recommend cuz the temp is perfect immediately 😂
