Like many others, I edited a pdf because the site advertised that I could "try" the service for free. It turns out this literally only includes editing- no saving, no exporting, no printing, no anything. Obviously, there is no reason to edit a pdf that one wishes to never save, export, email, print, or do anything else to ever again, except perhaps continue to edit it in a recursive loop of futility.
In my case, I wasted at least an hour on this site preparing an important document, only to find I would have to pay at least $20 to use the document.
I am now gritting my teeth and exhausted doing the whole thing over again on an actually free site, but I am not going to give this bait-and-switch, extremely misleading "business" a penny. It is not ethical to create these traps for customers to fall into, and it seems unlikely to be profitable for very long either.
I am not interested in any future dealings with this site, nor in any compensation except perhaps my exported, edited pdf in the next few minutes-- I only want to add my voice to the chorus of warnings to NOT USE THIS SITE.
