Summary: Great for setting the timer to something other than the cameras standard timer setting(s). Offers much more stable tripod photography over direct shutter release. Lots if different options with this timer make it flexible, however sometimes tough to remember how the different combinations work. Great product overall, but a little pricey (although you do get what you pay for).
Summary: I would recommend someone to purchase this product versus the ones made in Hong Kong. This at least comes with a warranty and you know what type of product you're getting when you go with Canon. I've purchased lenses before that weren't Canon and I swore from that point on that if I buy anything for my camera and it's available BY Canon, I would buy Canon.
Pros: Durable, Easy To Use, Functional, Lightweight, Portable, Reliable, Small
Summary: It does what it is supposed to do but the size could be smaller. I like hiking. I wish the size of this remote controller could be same as the one without timer so that it could be earier to be carried.
Summary: I'm a huge fan of long exposures and I've loved using plain tethered remotes on all my Canon cameras over the years (5D, 20D, 300D, A-1, AV-1, AE-1). This controller goes so far beyond a simple remote switch. I can't believe I've gone without this level of functionality up until now. All those long nights timing exposures by my watch are thing of the past!
Summary: I use this product mostly for time lapse and long exposures. I love the time lapse feature and the controllability there is with the features. Also the back light is very handy. It's a little pricey and big. In addition having a wireless remote would be much better.
Summary: I got this mainly because I have always wanted to make some of those exposure sequences where flowers open, the sun sets, etc. This device will do a great job of that. I'll confess I haven't used it much yet, but I read the manual and experimented a bit, so I know what it can do. It is an excellent smart cable release. I wouldn't call it a remote control, the short cable means you won't get very "remote" from your camera.
Summary: I use the TC-80N3 primarily for time lapse and for that, it works flawlessly. The only problem, and it's a small gripe, is that there is no power switch. It does not seem to be affecting battery life, though, so it's not that big of a deal.
