Here is a very brief review of the V2 Arbiter.
I ordered the saber on September 19th 2015 and it arrived this afternoon (18/02/2016) due to the "USPS" fiasco.
-The blade is 37 inch in length but i am unsure if it is 12w or 12+ because i ordered it long ago but it was eventually built after the announcement that they are moving to 12+ only
-The quality of the saber is far beyond what i expected, it is longer thicker and feels a lot more solid than i had anticipated.
-The soundboard and speaker are very loud and the sound is great when ignited.
-The picture's make the blade appear to be Incredibly bright although in person it is no way near as bright, to my eye it appears a lot dimmer.
Final summary
I am pleasantly surprised by the build of the hilt, it is incredibly well made and surprisingly comfortable to hold.
I realise that this isn't the most in depth review so if you have any questions please ask and i will be happy to answer.
