Additionally, I got it for only 95 cents, in MITB's sale. Pretty good value, I think.
It's made of quite firm plastic, and it's quite small. About 200mm from plug to plug without stretching. Ideal if you're charging your phone beside a laptop or computer. I'd guess it would stretch to about twice that length. See my pictures for how it was packed when it arrived, and what it looks like when plugged in.
Overall, great price, fast free delivery! Thanks, MITB!
