I bought JSK5, from Bomb's Jaina Solo Kotobukiya run, and I couldn't be more impressed with the job he did bringing it to life. The saber has tons of innovative touches throughout - like the recharge port in the covertec, TCSS V2 architecture, shine through switches, a removable speaker, and beautiful brass features. All the tech, including the CF7 w/ cex and double 18500 battery pack, is packed in really tight so it feels really solid and it handles incredibly well when paired with a 36" long thick walled 1" OD blade. Excellent balance and feel. 5 out of 5 stars.
