As a cup, it does it's job very well. It' fits together well and is leak-free, the insert helps mix, and as someone going from mixing my GG in disposable water bottles, it's nice not having to worry about powder getting everywhere if I'm not super precise with measuring it out. Not much more to say on construction, it's a cup, it does cup things.

As an aside, I thought the design was a sticker and was going to be disappointed, but thankfully this doesn't appear to be the case, just a high gloss plastic used. It's also nice to have a design that's not going to raise an eyebrow or lead to assumptions when I'm out and about.

It is a great shaker cup that I will use anywhere

The cup is good sized and the samples are tasty

A solid, good-looking cup. Wasn't too expensive either.

Looks, feels great it also dosent spill the water inside even when skaing it
