Heavy duty. Well worth the price!

This blender bottle really works well keeping beverages cold. And the lock on the lid is a plus.

Keeps your drink cold all day long. Ice doesnt melt as quickly as other insulated bottles.

Keep my smoothie cold and easy cleaning

These are great. They have a locking part of the lid. Quality made product.

I love it!big enough. Comfortable to hold, my drink stays cold for a long time.

Better than the plastic equivalents. More like a flask than a blender bottle

Solid bottle - better than the plastic version.

Excellent seal! Great buy!
