Just returned my 530 blower and exchanged it for the new 650 - LB6500 which comes with 5.0 amp battery and standard charger. Besides more power, this unit comes with some very nice upgrades : Starting with the blower tube, have added inner groves for a tighter fit - once its connected, you really have to tug to remove it. Tapered and flat nozzles are included with the package. The nozzles add some length to the main blower tube, allows more reach with less bending over to access the blowing surface. The most critical feature for me is air speed trigger which is now variable speed so the operator has full control of how much air volume is being applied. Speed/Lock On Dial : Can turn the blower completely off in counter clock wise direction, in clock wise direction - the dial allows you to regulate blowing speeds from 225 - 500 CFM , the motor will run without having to hold down the air speed trigger. Won't have to describe to you at this stage when you engage Turbo boost. The 5.0 amp battery is the upgraded one as well - has the fuel cells that provides 5 bars to indicate at all times the level of battery power and level of charge. The battery is much heavier - I was surprised how well the blower is balanced, felt good and was not over whelming. I am over the top with this product as its the most powerful and most advance unit Ego has produced. The only negative is the blower base - its smaller in size and not as sturdy as the 530, does not sit completely flush when placed on a flat surface, have added a green accent color to the base and makes it look nicer. Thanks for reading.
