It is a well built but overpriced $hocktech modified autococker. It is the full length body, unlike the SFL, which is a mini body. The milling is similar, but the Tremmor is heavier. They look very nice, and did I mention that $hocktech wants a lot of ca$h for one? Too much IMO. But you wouldn't be angry about getting a bum autococker from them. $hochtech makes good $tuff.
