An impressive extension! The Swiss Army Knife of it's category that you can't afford to not to use to fix layouts.
Ease of use
You work with an editor that is VERY easy to use (but it's also for not programmers).
Excellent and outstanding support; ready to answer my questions before the purchase to ease any doubts!
Great documentation and well explained, I had little to think over from the get-go.
Value for money
An investment that could not be better, the few dollars I spent were well worth it!
