I purchased .stls from Forward March Studios a while back. These .stls were for 2mm (1/805 scale) miniatures used for gaming. With that in mind they needed a pretty decent print quality to be discernable, beyond the capacity I have at home currently.
The prints I received turned out excellent. The seller was very quick to communicate with me throughout the entire process and sent me updates as different test prints were completed.
I'm extremely satisfied with the end result.
