He has a sufficiently long cable, a tactile feedback for focusing and when you press deeper, it triggers. This all works, of course without batteries. That's good for 10 EUR. If it comes from Canon, it costs five times. Then, the pressure point is pronounced, the lock for long exposures is rich, the control panel is slightly heavier. However, the features are still the same. So I decided: This nice part of China is doing it completely. When selling all kinds of equipment on eBay, I recently also offered a Canon-cable release. The original price was 64 EUR. Two years later he was tenderers worth only 3.50 EUR ... This can not happen to me with the prima funkionierenden JJC-part.
