Ready for a gamble?
I have had at least 5 projects running with them, only 1 was perfectly done. Rest were terribly coded.
Layout was random, and i mean basic things like were a Times font was needed an Arial was placed, were grey color text, black color was present, and more.
Plus you write a time consuming review with all the markup problems, and they don't solve all, or even make new mistakes which weren't initially there.
Some projects have ran for a week and still not solved.
There are many other similar services that transform a psd to html file, so i would recommend others.
