I think the Curve is a re-branded
istick isn't it? If so, I have the bending adapter on my
istick 20W and I like it. Two of the knocks on the 20W iStick were the threads, and the lack of a spring loaded contact.... the bending adapter solves both issues. It really doesn't add much bulk or length to the rig, and although I rarely actually "bend" it, I do like that I am protecting the threads on the iStick.
