Very badly designed; cheap materials.
on 29 January 2018
The instructions do say not to immerse in water (which, to me is impractical and unhygienic), but in just giving it a thorough rinse under the tap before the first use, a little water entered the space between the plastic mug and the inner metal lining, and I was unable to get this out. I tried repeatedly putting boiling water in the mug, hoping the trapped water drops would steam out again, but this didn't work.
The other major negative is the lid. It stinks of chemical / plastic, even after repeated washing. Not healthy. I can only assume it is made of poor quality material.
I can't understand why these mugs are as popular as they are and how so many major retailers sell them. I think this mug is very badly designed and made of poor quality material. It just looks nice. That's all. Mine has been disposed of.
