I got it with the rover board from 121c and its extremely nice that you can clip it right on the board so you don't have to worry about lose screws.
Used it once so far to tighten the trucks and does a great job at that.
Was a bit skeptical at first but was surprised right away on how well it works, I use it as my go to tool on the go
It does everything you need, lightweight practical.. "Nice clip". You can put it on your pants or nose either one will do...!!!!!!!
Found this tool to be well made and a great addition to on the go tool set but doesn't replace the ease of use that comes from a tradition skate key.
