It seems like this is the Gen II 80v blower per the part #. 145mph and 580 CFM. I'm not sure if 2.0 AH or 2.5 AH battery is included as the title of the listing and the description are different on that. I've been searching for blower deals but it seems that nothing much is going on right now so this might be an option. Usually the Gen I (500cfm) is $200 with 2.0 ah battery and i haven't seen much Gen II on sale anywhere. On greenworks website Gen II is listed as $149 for tool only.
Link by default sends to the seller CPO outlet and though it's $139 instead of $159 I opted to buy from Walmart for easy return.
