Hi Salley,
We’ve done development work and security on several of their themes and generally do not like them. Among smaller issues:
* underlying framework is so-so at best. Theme settings drop if you don’t do things in a certain “un-documented” order.
* updates are too frequent. Normally this might be a good thing however, Themify has updated some themes every 3-4 weeks and they’re often major changes.
The second point isn’t so bad, but when combined with other issues…
IMHO, look elsewhere.
There are dozens of vendors sellling better themes.
