Have you ever wanted to send a picture of yourself in a nightclub toilet to prove that you are having a good time...? Or a picture of yourself on a beach that isn't just City or Cottesloe to prove that you have been on a holiday...? Or just a complete family picture with you in it instead of sitting behind the viewfinder of the DSLR...to prove that you exist...?
Here is your chance.
These complete selfie kits have attachments for action cams, compact cameras, and mobile phones so that you can hold them out in front of yourself. Then you make your mouth look strange and away you go.
You can use them to bat strangers in the back of the head in a mall while taking your selfie and for some reason they accept it. Expect them to bomb your photos in return - in Japan they use two fingers to wave at you and in other places they use one, but expect the unexpected.
Oh, go on. Buy one. You know you are going to take selfies so you might as well do it on a semi-professional basis. If nothing else you can use it to put your phone under the bed to see if you can find where the other shoe went.
