I bought this remote for my Rebel XTI hoping for a remote that would at least take pictures...remotely. I read a few reviews from customers that were happy, but also from some that said theirs didn't work. Well, i decided to take a chance on buying it since it was inexpensive compared to the Canon remotes, but it turned out that I was one of the unlucky ones. I've tried everything and even replaced the battery, but I just couldn't get it to work.So my conclusion is this, if you don't mind wondering if you'll actually get a working product, give this one a go. If you want to be sure of what you're getting however, pay the extra money and get the Canon.
