I'm using the PressBook theme from them. It is a very clean WordPress theme with so many options and they provide a very quick support service. I recommend them for any web or WordPress development work.
They helped us set up again after a server migration where everything went screwy. Support expires after a year, but the support is reliable and fast. Plugin now supports turnstile.
I have bought their Pressbook theme. It's designed really well, and very well optimized. They helped me nicely with any problem I encountered with.
Answer: You can email them, all my support has been answered within hours, they don't muck around, they get right into it.
