The Lil Boss 20 Oz Vacuum Insulated Stainless Steel Travel Tumbler - Turquoise Blue

I have not tried it for cold drinks, but I use it for my coffee. It doesn't work to keep my coffee any warmer than my regular travel mug. My coffee gets cold just like a regular travel coffee mug. I thought it was meant to keep it hot all day or at least for a good portion of the morning. I do like the mug itself though. It is a nice mug with a great lid and easy to clean.Reporting back: the lid gets coffee stuck in it and it is very hard to clean the lid thoroughly.

These are awesome tumblers at a great price. I already have a couple of black Lil boss tumblers, and love them, so I ordered these as mothers day gifts for the important ladies in my life. The coating is smooth and flawless, absolutely gorgeous... the tumblers work very well, just as good as a yeti (I have both), but I have to say I love these more than my yetis because I am a stickler for a bargain. The cup comes with a nice tight lid with an open/close slider that is convinient for travel. The lid is not leak proof, nor does it claim to be, but it does offer better spill protection than that of a lid without the slider. My only complaint about the lid would be the difficulty to clean under the slide. I don't worry too much about my own, because I only drink water from my cups, but I assume that anyone who drank sugary drinks would get some form of bacteria build up inside the slider if they didn't soak it in bleach regularly.

The cup is great but the lid needs some work. After about 2 months of use the lid slides shut constantly when I try to drink out of it so I have to use a straw at all times. It's alright because I didn't buy it for hot drinks but it would be a problem if you extend to drink coffee or hot tea from it.

Is a little too large around for my hand and thus slips when I try to hold it. I put some stickers on it to get a grip. Leaks all around the lid and the drink spout, when beverage is shaken, even when I hold down on the lid. Wonder if can get replacement lid, but care instructions indicate this lid is designed only to fit this tumbler.

Good seal on top, straw fits Keeps ice cold for hours and hours. Not quite as good as top name brand, but really good for the price!

Scratched easily and lid didn't seal very well. Cups sold at Walmart were better quality.

I love this cup, this is my third cup I have bought and I love all of them. And this one is a really cute color, and when it falls all you drink stays in there. I just love it, in my opinion it's better then a yeti.

After a single day of use by my nine-year-old, the teal coloring started flaking!! Very easily scratched, etc.
