Ecotech Vortech Lot, three wireless quiet drives and two wireless Ecosmarts. The qd all run but seem loud to me maybe they need new bearings I've not heard any run other than these. The Ecosmarts both flash the stall light, not sure how that's reset or what causes it. They're all in complete state. $175 each, prefer to sell as a lot... No date codes on any of them.
