The shutter button is small and has a velvety surface. The material feels good and the portion is good in my hand.
Not only from the front, but also sideways work the trigger. However, I consider myself to close the NEX-7. A test up to 10m I did not do.
A battery is included and after loading and setting of the NEX-7 on "Remote Control" are ready to go immediately. I think it's good that only 3 buttons are available. The top "S" is used to trigger a single recording. This works fine. The second "2S" can be used for time-delayed recording (2 seconds, as the self-timer of the camera). The third is responsible for starting and stopping during motion picture recording; I have not used.
In the user guide the shutter manufactured in China by JJC is that the battery up to 3 years and up to 20,000 actuations works. The remains at least questionable from today's perspective. Because of my not very good "school-English" I miss a manual in German. So I can understand the instructions only passable.
The maker's mark "Quenox" irritates me because the actual manufacturer is loud trigger and the documents the company JJC. Whether there is a connection of Quenox and JJC, I do not know. Maybe it's just an incorrect description.
After short use I rate this trigger with 5 stars / points, because he works, feels good, easy and less expensive than the original from Sony is that I have not yet used. Should Set a lack, I'll update the review. Buying I can currently recommend without restriction.
Incidentally, these trigger for many Sony Alpha NEX cameras and is usable.
