The bottle is the best, until when we spout clean is needed. I believed that spout can be removed to be cleaned, but regrettably, I couldn't assembly it again. I've tried many times, but it was not possible, damaging the silicone spout. I've bought the bottle during a travel in USA (I live in Argentina), and we cannot but the lid replacement here. I suggest to indicate that spout is NOT removable. The bottle is excellent, but this issue caused that rating is not 5 stars.
