S'wellTumbler with Lid, 530ml, Onyx, BPA/BPS-Free Vacuum Triple-Insulated and Leak-Proof Travel Cup for Hot and Cold Beverages On-The-Go up to 12h Cold/4h Hot, Black

It's an overpriced tumbler. It is ok at keeping coffee hot for a while, but not more than an hour or so. 90 minutes and it's warm. It doesn't sweat. It's easy to clean, but it's not my choice for a slow, sip-your-coffee morning. I do like it for making a coffee in the morning, putting it in the fridge and coming home from work, adding some ice for a nice iced coffee.

Great insulation in the body of the cup but the lid is lacking in that and other areas. The rounded bottom great to fit in cup holders, not so great if tipping is likely due to work or other vibration. The lid slide breaks if you attempt to remove it to clean behind it also. Had to put another lid to use the cup now.

This tumbler is solid and well made and keeps drinks hot, but I'm unable to have the cover on when I take a sip. I always get a dribble on my chin or shirt with the cover on. A friend recently gave me a "Y" brand tumbler as a gift and it does not dribble when I have the cover on and take a sip. I deducted two stars for the dribble.

The lid leaks at the area where the coffee pours. So I drink my coffee without the lid.

I was looking for a good tumbler to have at home, and I decided that S'well would be a good option. I was not disappointed.This tumbler and the lid are a great combo, fit well in my hand, and I love that the Onyx coating matches my other Onyx line S'well products.
