Review on 🥤 Reusable Silicone Protective Tumbler Smoothie by Ryan Brunson

I bought this glass mug to make iced coffee and iced espresso at home. I chose this one because the silicone case has a "window" through which you can see the coffee. It's very aesthetic. The glass is great! It is sealed around the lid but can leak at the top if knocked over or held upside down. There is a hole at the top for the straw to flow through. Otherwise there are no leaks. It's also very easy to clean, and the silicone sleeve slips off easily, so it can be washed, but it won't slip off on its own. I love this kettle, I recommend it!
