i use them with no problems from my bottle warmer

Yes, you can use it. I tested my warmer with my platex nurser's with water in them and they did even melt then. They were fine in the warmer.

It won't melt the liner, but you need to be careful as the preset heating times will probably make the formula too hot in a liner -- use less water in the warmer than recommended.

NO! im using those too and unfortunately, it will melt the liners and milk will be everywhere. I like them though because , not much bottle washing and it's more sterile and convenient for on the go.

I looked into it when I was shopping for myself and you are not suppose to use the bottles with the liners in the bottle warmers.

You can't use use bottle warmer to warm-up bottle that have liner because two reasons the liners are to thin and the milk/formula will get too hot and burn your baby and the second reason is because the seals can reap open and burn the baby or even stain his/her close. Bottle warmers are only for solid bottles.
