Zak Designs DC Batman Comics 28 oz Vacuum Insulated Stainless Steel Tumbler, Non BPA Slide Lid Silicon Holder

Got this for my teenager for Christmas. He loves it! Keeps his ice cold for many hours and he uses it all day everyday. Design was made well and the mug is very sturdy.

Looks great. I bought it as a Christmas gift so I don't know about it being leak proof or keeping things warm or cold. I am sure my son (a big Batman fan) will love it.

Keeps ice cold for hours and keeps hot drinks hot for a while

I have this friend who is absolutely obsessed over Batman. He LOVED it and uses it every day. While I do not understand why cups can be so expensive, I am happy that it will be loved. This was a great gift.

I got this for my hubby.He needed a tumbler for coffee at work.It was actually much better than what I expected and hubby loves this tumble.

Looks amazing! Bought as a gift and was bummed to hear the lid looked like it had been dropped and had a small chip missing but luckily it doesn't affect the cup

Great Christmas gift

Outstanding!! Keeps my well hydrated throughout the day and keeps my drink nice and cold! Plus I love Batman so a definite win win!
