This was my first addon purchase for XenForo, after searching for quite some time. I did a lot of research on shop/item systems, and DBTech's is honestly the best out there right now.
It was extremely easy to configure and set up, and the language is simple to understand for myself, a native English speaker who does not know too much of XenForo's systems or code yet.
I also purchased DBTech's Credit system, which implemented into this addon with pretty much 100% ease.
I would definitely recommend you check this addon out, along with all of DBTech's other addons!
This is a big, ambitious add-on that does far more than we need, but it can also be configured allowing us to meet any user demand. I believe it was initially designed as a sort of forum "RPG" item system, so there's some wacky stuff in here, but it can be pared down to offer a few extra features for users with a cute little shop interface.
This is a FANTASTIC add-on. It does everything we need it to do, rewarding players for being part of our community experience. Customization feature is easy to set up - the entire extension is intuitive to use, even for a newbie such as myself. Keep up the great work, DBTech folks!
