I bought this as a gift for my dad who is a photography enthusiast. This was the perfect gift for him he enjoys it and showing it off to his friends thinking that he's going to pour coffee on his camera lens. When in fact he's pouring coffee into his camera lens coffee cup. The only drawback is that the base of this coffee mug is smaller in diameter than the rest of the mug which makes it tip over a little bit easier than other mugs he's had. But overall I think it's a great gimmick. And a great gift for somebody that has everything.
3 stars *** because the lid for sipping does not lock. Coffee will seep through it if the mug is turned on its side or falls over. The spill proof lid is as advertised. No liquid will seep from it. Little to no mess to clean if you accidentally knock it over at your computer desk at work. Just make sure you always Close the lid for sipping to minimize a spill if knocked over. Looks good.feels good
