Zak Designs HydraTrak 20 oz Vacuum Insulated Tumbler 18/8 Stainless Steel Water Bottle with Straw and Silicone Bands Tracks Your Water Intake, Travel Tumbler Splash Proof Lid (Black, Purple Rings)

This is a nice cup. It keeps 5 ice cubes for over 14 hours and keeps my hot chai tea for almost the entire night. It is still warm in the morning. That is what I require in a good cup.

The bands aren't as sturdy feeling as the plastic tumbler bands are, but they still work and it does a good job of keeping drinks warm or cold. The bands really impact my water intake

This has made counting my glasses of water per day an absolute breeze. The rings around the outside made it easy to count without removing them and it’s my favorite color!

I like this cup for tracking how much water I am drinking! Also, it does its job at keeping drinks both cold and hot! I love how it comes with a straw but also can be used with no straw. The only negative thing I have to say about this cup is that when left in my car for a few hours while working, the straw actually curved due to the heat... not a big deal just don’t recommend leaving in the heat!

This is an excellent mug. Large, smooth with gripper bands. My only problem is the weakness of my arthritic hands. I still had trouble gripping the mug securely because my fingers are weak. It’s beautiful and well made. I’m going to keep trying because it beats anything else I’ve tried.

I like the tumbler but don't like that the purple rings around the outside are always moving.

Great mug! I live in Texas, I can put ice in this at 7 AM and get off work by 5 pm and still have ice!!

It doesn't sweat and allows me to keep up with how much water I have had during the day.
