The product itself is pretty good, worth the price. My biggest aggravation is the confusing account interface (when logging into account details in a browser); everywhere shows a "free" account (even though this is a paid version) and you only get access to 1 device at a time - even though in multiple place in account details it looks like there's access to 4. Nope, those are really just "ads" wanting you to buy their "new" membership deals. This is not a review of the terms of the deal - it's a review of Customer Service's handling of my issue with what I thought I bought. Customer Services is very difficult to communicate with - they take a long time to reply to inquiries and their English is poor, making it hard to understand them. I do not recommend. Spend a tad more for a PDF platform that's clear on what you get - preferably by a developer in your native country.
