Wide range of functions

For the price the little thing has a lot of possibilities. Delayed [in seconds, you can adjust] trigger, shooting etc.
This remote shutter release can be very good night shots or shooting make the starry sky if you want to expose more than 30 seconds (maximum at DSLR's). One can thus make really great, provided with circular lines recordings from the starry sky, but you just have to expose loose several minutes, if not half an hour or longer.

The only drawback: With longer exposure times will then often appear in the image information a slightly different from the set (the remote release) time illumination duration. For example, if the remote trigger I set 300 seconds and the recording is finished then, I look at the image information and since then stands at a time 303 seconds. This difference is however at exposure times of less than 1 minute, very low (less than one second) but is just greater with longer exposure times. So since either my 70D seems to measure time differently or just the remote control. But I do not know why that is, is not annoying
