Used to be you got good stuff at Ebay, no more. Recently I bought a six year old CO detector, noisy fan that was listed as quiet running, a small lead acid battery that has been sitting on a shelf for two years. The first one was DOA so they sent me another which works but is old also. I complained to Ebay about the sic year old CO detector because someone could get killed but they are still listed.
Ebay now has as many scams as Craigslist IMHO. I'm thinking I'll buy more from Amazon. They have reviews about the product not just the seller.
I predict sales will fall and the stock will follow.
