Blower Air Duster Main Unit

I purchased this a few months ago to clean my Roomba's filters, but it was too large, so I am selling it.
There were no issues with the airflow, and I used it a few times.
The battery was not included from the time of purchase, but a battery of the same type as Makita's could be used, so I think a compatible battery for Makita could be substituted.
