I have the guardtower, outhouse and some fences. I do think I bought everything from Zealot miniatures though. The casting quality is very good. I had a minimum of cleanup to do. They can be a bit fidly to assemble as there are no slots for assembling the walls. They just "bump" up against each other and you have to align them yourself and keep them that way until the glue has dried.
I have made and glued in some 90 degre wedges to help with that and to add some stability to the structure.
I would recommend them though they are great value for money.
