Not sure why anyone would write anything negative about this perfect mug. I've purchased countless numbers of mugs that are advertised as thermal and drip proof. The Nissan lives up to those terms and then some. The high quality construction makes this a very attractive mug. I can leave it on my counter filled with a a beverage and ice for 10+ hours and discover that the ice is still solid and the drink as cold as when I last took a sip. The cover tightly screws on resulting in an impenetrable seal. The snap fit cover for the drinking hole is so tight it has never opened the countless times I've dropped the mug on hard surfaces. As long as this mug is made, I will never purchase another. I have found my thermal mug nirvana.
