got the new "whip" in mail today from unimax.....used it for a few hours on a black and grey piece i was working.....runs pretty nice on low voltage 7.5 volts (in comparission to the 8.5-9.5 i run my neotats at)...the tension clip thing is cool and will take a lil while to figure out, it adds a "springy" effect to both ends of the needle stroke and really makes shade variations easier to lay....i look forward to working the hell outta this thing
