My humble ideas for improvement on this cup include: 1) having a non-skid and/or thinly protective bottom surface on the cup and 2) a better grip surface on the accompanying lid as well (I have almost dropped mine several times already) and 3 )again, a slight grip surface or indentation on the cup itself (it is a beautiful design but slippery). I like the ingenious infuser design and its excellent quality.
Love the Cup, perfect for on the go, in the car, in the morning. Not as happy with the Infuser, the mesh isn't fine enough and all.the small tea grit falls into the bottom.of the Cup, so I never get to enjoy the last few sips. I would have thought the mesh would have been tested before distribution?
