The Lil Boss 20 oz. Vacuum Insulated Stainless Steel Travel Tumbler (Matte Black)

This thing is absolutely amazing!! It keeps your coffee (or tea, or other hot beverage) hot for a REALLY long time. And if you should put ice in it for a cold beverage, it will keep that cold for a really long time, too! Don't waste your money on the super expensive tumblers. This tumbler is absolutely 100% worth the money and is an amazing value. Definitely recommending to all my friends!

Love the mug,the cover however doesn't seal well. The part that slides on the lid leaks whenever the mug is knocked around and the lid doesn't fit that securely. I am sure if it was knocked over it would come off.

Expected this to keep my coffee hot for most of my workday hours based on website descriptions and review. Coffee was lukewarm in less than 2 hours. Returning this product, Very disappointed.

3 stars for being okay.I needed a tumbler to drink more water since I work a desk job. This fit the role perfectly and isn't as crazy expensive like the Yeti.It keeps my drink cool and doesn't sweat.The reason why I took 2 stars away is because of two things. The first is the tumbler is pretty slippery. I imagine with the black/colored coating it would add some grippyness but it just makes it slippery.The second and most important issue is the lid. I like to close the sliding lid because I don't want dust getting in, and opening it when I want to drink. The lid as a little lined lip that retains some liquid/water after you drink. When you close the sliding lid on it there is a snap as the plastic locks in place. In return, the tumbler flicks the retaining water forward all over you/your desk.

Great tumbler. Keeps everything super hot for many hours and cold for days. Only thing I don't like is that it's difficult to clean really well under the rubber kid seal. My order arrived fast without any issues. Would highly recommend you go with this one and save $ over the big brand name ones. By the big boss tumbler for larger drinks. You won't regret it!!

Overall, I like this cup as much my Yeti. The only complain I have is that the lid is little loose.

From what I can tell it is equivalent to the Yetti (?) for about 2x the price. I use it for my coffee. Pour it in early in the morning it is still fresh, hot in the afternoon.

Not a very good tumbler it doesnt keep ice. Im so disappointed
