Design changed from pictures. Sometimes leak proof but also drink proof.
I got this yesterday and am sending it back immediately. The design of this lid has changed from the photos shown on the Amazon listing and on the manufacturer's website. The lid is extremely difficult to thread onto the cup. You almost have to be the Six Million Dollar Man to remove or install the lid. I had to slide the cover latch open and use it as a lever to actually screw the lid on or off. The inside of the lid mechanism has a double ended seal gasket that can be taken apart by rotating a locking knob to the unlocked position, but when putting it back together, the gasket will either seal off the fluid so that you can't even take a drink, or if you stick your finger inside the bottom of the lid and move the gasket so it's not sealing the hole, you can drink, but then it's not leak proof when the gasket isn't in it's correct position. It will pour out with the sliding latch in the closed position.The item pictures look like a good simple design but this cup doesn't have what's shown (compare with my pictures) and is not a good design at all! Shame on Thermos engineering. It's not worth the $15 I paid for this on sale on Amazon. I had thermos cups in the past that had the best cold/heat retention of any cup I've ever had (easily 6 plus hours hot and almost 12 hours cold), but the lids weren't easy to get clean and got stinky every so often until I did a drastic lid disassembly to do cleaning. I was hoping this new Thermos cup would have more easy cleaning and also have the same hot/cold retention of the previous Thermos cup! But this new one only kept my drink hot for about 3 hours. I sip my hot tea all morning at work but this one didn't do the job.Instead, I just got two awesome Contigo Autoseal mugs that have a smart and functional design and are easy to clean. I actually bought them at a local store where I could see and touch the cup and open the lid to see how it functions and if it's easy to take apart. Great so far.
