Its size is tiny (2x3 cm), it comes with a small bag that attaches the strap to the camera: no chance of losing and immediate availability.
You have to activate the camera timer / remote control mode, it is immediately functional.
Two modes are available: immediate shooting and a shooting after two seconds, very convenient to hide his hand. The selection of this mode is done using a small switch on the back of the remote. There is therefore only one button. We can not do more simple and functional.
Shooting is possible despite the far infrared. The price difference with a generic remote control is low, I recommend this model.
Manufacturing is well made, the cover is very well thought out.
