Thumb Score: +12
Great deal if you need another battery as well as the tool. This is a set bundle so no hacking, but for $ 139 for a good Fuel tool and maybe the best battery in m12 lineup, some may find this useful.
You can also get the tool for $ 99 if you hack the current promotion but for $ 40 more for an XC 5.0 battery it seems pretty good.
