The seller packed the item with bubble wrap so secured. Really appreciate it so much. Box is not dented at all. They shipped it so fast once i checked out the item. The delivery service is better than the other seller so called Stanley-official-store.

Well on to the review, the color is gorgeous. This is my 3rd Stanley tumbler. Invest in good tumbler and it last longer.

As per my video, easily can open with one hand as I was recording on my other hand. hope that answers your curiosity about the tumbler. Got amazing discount on 5.5! Thank you again seller!

I love my new ice flow! I recently purchased and was using The Quencher. And while the quencher is nice and solid, as well kept your beverage cold, I personally found I was drinking less water due to the straw. Not to mention it was a heavy to lug around by the handle. The Ice Flow opening is easier to drink from than the straw and my water intake has doubled because of this. I love the handle on this one, it is much easier to carry around and yes it does stay cold same as the quencher. In fact, my niece and sister have both replaced their Quencher’s for the Ice Flow. Bonus, no wrinkles…drinking from a straw may cause wrinkles around your mouth.

It's taller and narrower than I thought. The deal breaker was that the lid and drinking spout were molding!!!! I washed them in the dish washer, and after sitting out to dry, I losely put the lid back on. When I went to fill it, a week or so later, i noticed all this darkness on the lid! Washed it off! Gross.
Apparently, the lid is not microbial - I contacted support twice. Once they sent me cleaning instructions, the second time they apologised. I"m planning on returning them.

My daughter picked out the mint color, which is a really pretty color. Stanley cups are popular with the teens. My daughter’s old Stanley (different style) lasted about 16 months with use 5 days a week before the coating started to peel/chip off. I personally feel that the competition brand holds up better, but this is what my teenage daughter wanted. This is a different style cup, so we will see how it holds up. If it is like her old one, it does keep drinks cold.
