The Hama-wrist strap is for mobile phones, normal small cameras, voice recorders, etc. certainly the ideal part. The loop is not connected via a plug / carbine with the device, where you then always have to have the feeling that the plug could work. That the small metal particles could cause harm, I can not imagine. On my Nokia phone a similar loop factory was going well with metal, but has not yet been done no harm (in two years). Overall, good value and better than I had assumed.
