NothingButSoftware offers the refurbished Logitech M185 Wireless Optical Mouse in Swift Gray, model no. 910-002225, for $8.49 with free shipping. That’s the lowest total price we could find for a refurbished unit by $4, although we saw one for 50 cents less in Janaury. This 2.4GHz portable mouse features a nano-receiver and requires a AA battery.

Of note, no warranty information is provided.
