The review would have been 5X but the first brooder that came was faulty, which created a serious problem for the chicks that were in the old Brinsea,the reason for getting a new brooder was my old one was changing temperature a couple of degrees,which is not ideal.Sadleydue to the new brooder being faulty the chicks stayed in old one 2 extra days and Sod’s law it shut down to 26 degrees while we were out and the chicks were very cold,my wife warmed them up with a hair dryer, I have to ask how often can I put the Anion on,ie how many time a day etc.Also I would like to again thank Tony for his customer service.could I get a reply about the Anion.
