Question: Does the lid opening lock or close to prevent venting heat?
Document: It's a horrible product the lid leaks and does not close all the way!
It is ceramic so it doesnt hold heat very well and my lid did have a mild odor to start with but I soaked it in hot soapy water for an hour and that fixed that. Its made of a silicon material that I wouldnt trust to dishwasher soaps and heats, I fear warping. The lid definitely does attract dust, like another commenter said, and its very visible, but thats ok, it doesnt interfere with my coffee enjoyment.My first order came cracked and broken top to bottom.
Tumblers are fine but the lid is unuseable! It tastes terrible! I am looking for a way to use as travel mug without lids.
Just use cation...the cup gets really hot even with the sleeve! And I don't use the lid because I don't like the taste of silicone.
The cup is great, but the lid has a funny, chemical smell to it. Ugh. Exactly why I ordered it, to get away from that plasticy odor and feel. Oh well.
A HUGE pain in the bottom.So if you can find a replacement lid that is a tight sealed fit (which I am currently looking for), you can eliminate the weak link of the lid and you would pretty much have the perfect travel mug.
The lid tastes so gross. I've had this and have been actively using it since Mother's Day and the lid taints my coffee. I travel with the lid on and then take the lid off when I get where I'm going and drink my coffee with the lid off.
It's much smaller than I thought it would be. The cup is very thick, not leaving much room for contents. It says it's 16oz, but it holds maybe 12oz of coffee.The lid is also quite overpowering. It's silicone and it has that heavy chemical smell that takes over any coffee goodness you might want in the morning.Not recommended. :-(
So I work in a lab and I used my access to super precise scales and such to measure the maximum amount of liquid this mug can hold, and that would be 14.3 ounces. All that being said, I love this mug. Its heavy, solid, doesnt change the taste of my coffee, and so far the lid has never dripped or spilled.
I bought the cup for my commute to work. I used to use thermal mugs that stain with coffee and have the bad aftertaste of old coffee and metal. This cup is great. It is ceramic so it will not stain like metal ones. the silicone sleeve is great when the content is hot. The lid is also very good. It does not leak. Great cup!
