These are great cups. I have been using them for several years. They keep drinks cold all day and night. The locking lid is very secure.

Work as described. Mixes well, keeps contents cold for hour, easy to open, and screw on the top. Very happy with this product.

Bought as a gift for my son and his wife. They love them. Easy to mix their smoothies and a breeze to clean with the bottle brushes.

Love love love these insulated Blender bottles! They keep things cool and are light weight. I especially like the locking lid!

Great buy! Your normal blender bottle but now it stays cold longer. I’m obsessed, you it for all drinks beyond protein shakes.

Great value. Pop up lid so easy to use. Looks real nice and durable. Great exterior material as well as the stainless steel inside

First of all: cute! Also fr keeps bevs cold. Love the locking function so I can just throw this bad boy in my bag or car. No complaints!

purchase this to make my protein shakes after my workouts and they are great. I really like them and the price was very good for the great quality.

I have 4 of these, and I use them everyday. They are good quality and they keep my drinks cold with no condensation build up on the outside.

bought these for my husband and they are his favorite he usually pays 21 for just 1 so this price for 2 is great!
