This genuine Canon RS-80N3 is Canon's official remote cord for their better 35mm and digital EOS cameras. These cameras take an "N3" connector, which has three very fine pins.
If you've got a midrange to top-end EOS camera, this is the smartest remote cord to get. It's small, light and simple.
The TC-80N3 is a more complex verison with timers, but for long Bulb exposures, most Canon cameras clock the time on the top LCD.
The RS-80N3 has the same two positions as your camera's shutter button: half-press to wake the meter and focus, and full press to shoot.
The RS-80N3 locks for time exposures simply by pressing and pushing forward.

The "N3" plugs and sockets are somewhat flimsy, but on the bright side, they click-in and remove much faster than other kinds of screw-in remotes. They are also always locked; they won't pull-out unless you grab the silver outer case and pull to unlock and remove in one motion.
I'd really prefer a real screw-in mechanical cable release, but as these electronic cables go, this is much better than Nikon's multi-step screw-in affair.
The Rebels take a smaller plug that looks like a 2.5mm microphone plug. This remote doesn't work with the Rebels.
The earliest 1980s EOS cameras take a different cord with fatter contacts on the camera's socket, called a "T3" socket:
Old-Style 1980s Canon "T3" Remote Socket. Does not work with this!
This RS-80N3 cord will not work with cameras with the 1980's T3 style connector. Use the 60-T3 cord for those cameras.

It just works.
It's reasonably easy to attach and remove; far better than having to screw it on and off as we do with Nikon's remote cords.
$45 is a rip-off, which is why there are so many knock-offs sold for a fraction of the price.
Yes, you can buy cheap copies for under a dollar, and good copies for $17, but if you shoot for a living, it's worth getting ripped-off for $45 so you never have to waste time with a crappy copy that stops working.
One caveat is that the camera's pins are as delicate as a CF card socket's pins, and if you make any mistakes with a 75¢ knock-off and bend the pins in just the wrong way so the shutter is effectively always pressed, you could completely disable your camera!
It attaches by orienting the plug properly, and pushing straight-in on the center of the black part of the connector.
To remove, pull straight out on the silver outer part of the connector.
When you connect it to your camera, pop the rubber socket plug from older cameras into the receptacle in the back of the remote switch so you don't lose it.

Its shutter button works exactly like your camera's shutter button, with the additional feature that once pressed down, slide it forward to lock for time exposures.
I've resisted for 20 years buying one of these, but I finally did so I could make long exposures. It's not worth it to me to take a chance with a crappy $10 cord that might waste more than $45 of my time if it croaks on me at the wrong time.
Be very careful to have the correct orientation before inserting the plug. The pins on the camera are very thin, and I worry that with repeated use eventually that I'll bend my camera's pins. This is another reason I won't try a third-party remote; I'll feel real stupid if I save $44 with a $1 cord and ever had a $241 repair bill to replace a broken camera socket. If you bend the pins in the camera's socket and they short-out in the same way that tells the camera that the shutter button is pressed, the poor camera will just keep shooting until you do something drastic, like break off the offending pins. Be careful!
If you want a more complex unit that adds a timer for long exposures and a whole lot more, look at the TC-80N3.
