I need a plugin like this but I seriously doubt

The options for this pluins are incredible, but I have serious doubts buying it, because before buy here other plugins and still not working, well I've tried three different servers, but without positive results, one question, do you sell real plugins or just wonderful ideas?

I think they should change their model of doing things, this is your business, and if lose customers eventually disappear.

This is not a criticism with a bad attitude, I'm a good shopper, but I obviously like to trust what I buy.
