"The lego water bottle is a great addition to the school lunch box or a stand alone water bottle. Although it says its for "youngster" I couldn't resist getting one for myself. The product feels great and is of excellent quality. The only thing I had trouble with is unscrewing the drinking lid. When I try to take a drink and unscrew the drinking cap the lower portion unscrews as well. So i have to hold down the middle part to open the cap. Other than that I love it! I hope Lego will make a more elongated water bottle to hold more water. Or a larger bottle for adults. I would definitely buy a few."
