Ordered instead of the original Canon twice as much (or so), the quality seems very good; on first use I had slipped the spade-head switch on the flash shoe, and therefore no contact, I thought it was a failure! Too bad there is not some kind of "keying" it would have saved me a fright! Then when we understand in which direction the insert (the cord "sort" lens side), it's easy to put on and to remember (if we look at how the switches are arranged in a row and found the right way to align all). The downside is that for those who do not regularly use it of course, then with a regular use it is no longer a problem. In short, overall very satisfied!
