You pay to get updates!

The plugin itself is okay, but their policy about updates is wrong. Basically, if you want to get updates of their paid plugins, you have to pay annually. The usual policy for other paid plugins is you pay once and get free updates indefinitely, only support is paid. Imagine this situation: you have paid for a plugin, one year elapses and a security issue or another bug is found. And you are forced to pay because of their bug/security hole.

I have another complaint – they are not polite to customers. They reply in angry, accusative manner to emails when you state your discontent.
