My trusty headcam expired on 16 August and after trying the alternative of filming with my iPhone, using a neck hoop to mount it, I decided that that didn't really work. After considering other options, such as using a static rather than body-mounted camera, I opted for a GoPro camera, which I'm hoping will give far better results when mounted on the neck hoop.
I didn't replace the headcam like for like as I felt it was unacceptable that it had failed after just only three years of use. Fingers crossed the GoPro will last somewhat longer.
