Yesterday, I took delivery of this simple gadget, designed to enable even the most wobbly of us to carry drinks safely. I have to say it's brilliant. I can safely carry a hot cup of tea around the house, without even thinking about it. Not bad at $12 as well. They delivered to me here in the UK, without any probs.
I have one at work it means I can carry my own drink from the kitchen to my desk which is miles away I love it, my work colleagues call me Florence nightingale as it looks like I'm holding a lamp. Great gadget :-)
This works for you. I would shake holding the arm. I constantly shake so have lot of problems,but like you always looking for useful things to share with others.well done
