Query: Initially loved this thermos, but now not so much

I read the previous reviews before purchasing this thermos for my daughter and most people seemed pleased. Although there was some concern of this thermos leaking, I thought that was unlikely. Initially, my daughter LOVED the thermos, she said that is keeps her drinks hot all day and it was perfect for her; however, I now know I should have listened to the reviews because the thermos has started sporadically leaking. The first time it leaked, she was wearing a white top and the thermos leaked hot chocolate on the front of her. She thought that maybe she didn't tighten the top correctly. Since then, she has used it a few more times (being a bit more careful) and it still leaks randomly, not sure why. I would have given this item 5 stars in the beginning, but since I have to now buy a new thermos just a two months later, I can not give a good rating for durability or cost since it was too expensive to only last two months.
