Yes, I'll be honnest with you, in the begining I did not believe it.
I was thinking that these guys will take my money and leave me with just another Wordpress theme. I finally chose Spike Theme and I payed with Paypal.
Turns out it's the best thing I could spend my money on. The theme is very good in code, very fast and has a great and responsive layout. I had some issues with the files and I received help in very short time , fixing all my problems.
Its the best theme I had since I started blogging in 2005. Few years back I had to pay a lot for a new theme and for customisation.
