I want to get one and was thinking about wearing it 24/7 but then remembered that I put on lotion after every shower. I'm thinking that would make the cord gross if I don't take it off, and it seems like a hassle to have to take it off every time as it doesn't seem easy to get back on and adjust to the right length.
When you get used to it, it's not at all difficult to put on or remove. I like to wash mine in the shower when I wear it, and hang it on the radiator while I apply body lotion. My baby pink cord hasn't discoloured or frayed at all. When I last visited a Cartier boutique, I was given multiple cords to take away, so I now have fluorescent pink, fuchsia and lime green available whenever I fancy a change.
