I have gotten 4 mystery boxes. 3 of the $75 and 1 $200. I just choose not to do unboxing videos. The $200 was a Dark Sentinel in GB with Lite sound and Silver FoC. The $75s were all stunts. Dark Apprentice LEv4 in BR with windows (this became a staff) Dark Initiate LEv4 in GB and Archon v2.1 in CG. All sabers had AV switches.
Well, I guess we are on the same boat when it comes to the MB that we bought from Ultrasabers.
I also have 4 MB (3 are from $75 and 1 from $200). Dark Sentinel v4 GB with silver FOC no window w/ AV switch ($200), 1 Sentinel v4 BR with window and AW switch ($75), Dark Apprentice BR with window and AV switch ($75), and finally the Dark Mantis AB ($75). I think it would be awesome if you share your unboxing experience with the saber forum community.
Are you planing to get more MB from Ultrasaber in the future?
