About to buy either the LB6504 or the LB5804. Reading the specs, it appears the 6504 is an upgraded version of the 5804, so I can't figure out why it's less expensive (not by much, but still) at HD. Am I missing something? Thanks for your help.
Autonomy-wise, with up to 30 minutes of autonomy on a full charge, the LB6504 is on the low end when compared with other cordless handheld units (the one with the best autonomy being the EGO POWER+ 580 CFM LB5804 with up to 180 minutes of runtime).
