I would keep it at least a year then if you find you never use it sell it, I not sure why all of the sudden if you don't own brushless it's junk, sure brushless it awesome but there not without problems too brushless motors do not like high heat and they are new in tools time will only tell how well they hold up, I still have my grandfather's old metal case drill from Im guessing the 50s plug it in and it run's like new, so brushed motor's last.
But Iam happy everyone is drinking the Kool-Aid because the prices of the brushed Milwaukee is dropping like a rock,
