I am going to list out the Pros and the Cons about this tumbler. The first Pro is the black matte color and texture, the security of the top and straw and the sleek design. The only con is that it is not dishwasher safe, other than that, I really like this cup. The top is the type that you have to screw on. I think they do this to make it leak proof, that aspect is great, especially because I have two small kids that will use the cup. It does make it a little hard to remove but over all I would recommend this cup.
