S'well Stainless Steel Tumbler with Slide-Open Lid, 18oz, Onyx, Triple Layered Vacuum Insulated Containers Keeps Drinks Cold for 12 Hours and Hot for 4, BPA Free

I love S’well products! They are of high quality and really keep your drinks hot or cold for a very long time! The lid fits perfectly and there is no leakage at all! Highly recommended!

This tumbler will keep drinks cold for at least 12 hours. It lives up to the hype.

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.

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.

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

I really enjoy this cup, keeps my drinks the appropriate temperature!!

It was weird...the coffee didn't stay as hot as others I've had, but it wasn't as warm on the outside as those others...which you'd think it'd be, if the heat was dissipating faster. I'm guessing the lid isn't the greatest. It's still good, and the quality is good, so I'd consider if price is right.

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.
