Reforce Stainless Steel The Joker

I went from having a basic plastic shaker to this. Must say that the difference is there. As some other comments already mentioned if it is not screwed correctly - expect leakages. Even then, I would carry it as if it were to spill anytime. I like the rubber padding on the bottom of the shaker so that it's stable on surfaces.

The metal is quite thin so the drink gets cold pretty quick but also takes on heat very quick. I did not expect that at all and am pretty disappointed.
Also it deformed after forgetting it in the freezer and became leaking.

Tålig och snygg shaker.

Hin und wieder mal undicht, ich glaube man muss den Deckel schon wirklich bis zum letzten anziehen, allerdings mit wenig Kraft, sonst hab ich das Gefühl, er verkantet und wird deshalb undicht. Ansonsten gutes Produkt, allerdings nur 3 Sterne, wegen der Unzuverlässigkeit der Dichtigkeit.

Is a nice looking cup
Lightweight
But unfortunately doesn't matter how you place the lid if you shake it it leaks
So not leakproof!
