Be careful. The spam reply I received said the person had two just sitting in the garage not used for a couple months and the girlfriend wanted them gone. He said he couldn't figure out how to post a pic on freecycle so he included a link to see the picture on another site. When I clicked on the link it took me to a site that you had to 'complete this free offer' to join in order to view anything. Needless to say, I didn't complete any offers or reply to his email. Spam, maybe something else, not taking that chance.
Yesterday I went to pick up the bator. It actually is a Aluminum brooder unit (the stackable kind) it looks to be in pretty good shape. I had an EMT class last night so I had no time to test it out. I will do that toady and report here/
