Anyone tried pur storage bottles? I hear it's really good for breastfeeding mums

From the product information: Capacity - 125ml / 4oz BPA Free Can be sterilized Can be stored in fridge or freezer Can be reused Leak proof with air tight sealing caps Have panels for easy writing Compatiable to Medela, Ardo and Ameda Breastpump It seems like similar to other normal brand of BPA-free breastmilk storage bottles. If you have space in the fridge or freezer, you can invest in these bottles. However, other than space storage issue, you need to sterilize the bottles before and after each usage. If you are looking for storage friendly and time saving storage method, I would recommend to use disposable breastmilk storage bags. These storage bags are BPA-free, pre-sterilized and not taking up spaces in fridge or freezer as compared to bottles. For me, I like certain brands like nanny, pur, medela and honeysuckle. Honeysuckle is highly recommended as it can be attached to your breastpump directly through an adapter and device and it is very convenient. I purchased mine from qoo10.
