The plastic housing of the trigger makes a good impression, except for the battery compartment cover seems a little loose.
The batteries capacity translucent with its two AAA batteries to keep forever, but there is unfortunately no battery indicator on the display.
Set the timer to start with a simple keystroke, unfortunately there is no ON / OFF switch.
Included with only an English manual can be found. But there is a detailed video on YouTube, which was provided online from the manufacturer. (Search term: Ayex Timer Remote for DSLR camera)
Overall, I can say that it is a super product is the price-performance ratio.
