    Hit and miss

    The first couple were not to my liking. ARFTAC was great and exchanged them quickly, with much better replacements. Great vendor!

    Microbeast Chrome BCG

    One of the best bcg's out there and an incredible price through arftac. If your running cheap nitride or no name nib bcg's stock up on these as replacements while they're still available at a very reasonable price.
