Bests & Worsts Reviews from Amazon

not sure if its an error on my end or the lid, i have a large mouth 64oz cup that i got from work ( no idea on the brand), but this lid fits it well but does not seem to screw on deep enough onto the cup and after about a weeks of use the lid does not seem to sit on the threads of the cup and when i screw it on or flip the sip lid open it now leaks from that area. after xmas i will try this on my daughters hydro flask and see if there is any difference im sure if works well on the intended brands but i feel it does not screw on enough times for my cup (about 3/4 to a full turn until tight) the packaging however was very presentable/giftable and the price was great for the product.
