I have a bunch of their plug-ins, and they're great.

That said, as the previous poster indicated, their customer service leaves a whole lot to be desired. Lots of hidden upcharges, almost impossible to transfer your licenses if you get a new computer, etc.

So far I haven't encountered any nightmare scenarios myself, but I've talked to enough people who have to be aware they exist. But as I said, they are great plug-ins as far as the functionality and doing what they say they'll do. Quite a few of them are "go-to" plugins for me.
