I was excited for this cup. The lid doesn't stay on or seal tightly. If this was to tip over the lid would easily pop off . Horrible make.

Absolutely love this Tumblr! I love that it’s glass and I love that it has this insulated stainless steel piece that you put the glass cup into to help keep it cold but protected as well. Super love that it fits in the cupholder in my car. It is not leak proof so keep that in mind!

Love the glass only drawback is the straw it is plastic would’ve been better to have a glass straw

This cup is nothing like what the ads say about keeping drinks cold. I feel it up with ice, add my cold brew and the ice is gone within 30 mins. I have even tired putting the outer sleeve in the freezer and doesn’t help. It’s a cute cup. But not worth it. The photo I attach is less then 30 mins

I immediately have fallen in love with this cup. Not crazy about the giant straw but that is not a problem. I have so many straws I can use. Love the design and the fact that it's glass and it will stay cold because of the metal sleeve it fits into. I will be buying more.

Extremely disappointed that I got this. The lid does not stay on secure at all my whole coffee, spelt. And I did everything that was instructed. It also has condensation on it in the glass part. And dripped down to the metal part, which makes it slippery.
