Review: Fine product - Purchased to use in vehicles that have small cup holder spaces, like the Mazda CX-50. Fits great, and it's leak resistant and keeps liquids cold. Just watch out that the rubber band hooking onto the lid doesn't come off.
Review: Perfectly sealed and spillproof! Just what I wanted! - This is great for use anywhere that you want to prevent accidental spills or leaks. Keeps ice for hours and don't have to worry about it spilling. Plus it is great for camping, hiking, etc. You can set it down and because it is completely sealed, you don't have to worry about nature "intruding" ants can't get in and if you are used to hiking or being out in nature you know that can be a big deal, keeping insects out of your drinks. I love how this keeps my drinks cold all day and has really reduced how much ice I have to use because it keeps ice for so long. So I've taken to using it as my 'everyday' cup. So I will also be buying more of these to putting with my hiking/camping gear for my own use as well as the use of my kids. I haven't tried using it with hot drinks yet, but with winter coming on I will probably be doing that soon and will update how well it works with hot tea and cocoa (not a coffee drinker but if it works with tea, it should work for coffee as well).

## Features

- Triple-insulated stainless steel keeps drinks cold for up to 24 hours and hot for up to 12 hours, perfect for long days at school, the gym, work, or travel.

Pretty good cup. Kept drinks cold for a while but the stopper thing in the lid comes out wayyy to easily and eventually got lost
