I'm decluttering my parents' house. I will not sell items individually. These items were on display and I believe they were used only a little. The items in the images are all that are included; there are no other accessories. I have not tested their functionality at all. One unit has a broken caterpillar track? I probably won't be able to answer any questions, so please make your judgment based on the images. Please understand that these items are sold as-is, with no returns, refunds, or exchanges. If you don't understand the meaning of "junk" or "no returns, refunds, or exchanges," please refrain from purchasing. I will remove some dust before shipping, but please assume that the items have dust and dirt on them. Thank you. m(_ _)m
