invictawatch.com é seguro?

I trust the site, but it's whacky. For instance, I have an Invicta that the site is now saying doesn't exist. But it does exist and the warranty registration still appears, just without a little photo of the watch, and then, when I click to "see more...," I'm informed there's no such product. What--then--is it that I registered for warranty? The registration was successful. There was also an occasion when I couldn't log in, even though UN and Password were correct. That had to be fixed by their website manager. I'm not sure whether this means we really can't trust the site. It's not some fraud or anything like that. It just doesn't seem to work very well.
