“My Calix cup is absolutely beautiful to look at but not so practical to use unfortunately. Firstly it comes with a metal lid which isn't the best idea when using hot drinks, the lid becomes very hot and its easy to burn your lip.
My second issue is that it doesn't seal, what is the point of a travel cup that spills on the move?
In a nut shell it is the perfect cup when sat stationary at my desk, with the lid off but not great for on the go hot drinks.”
“I bought the calix . I'm please with it . However I bought it to put in the side pocket of my rucksack to travel to work on a motorbike. Unfortunately the lid is not spill proof so cannot use for intended purpose. Other than this it is very good quality”
