I am considering buying an incubator and there is one on ebay that is octagon in shape and has a clear top on it. It looks entirely cool because we could really watch the hatching. I'm too new to byc forum, so I can't post a url, but the item # is 270737695636. I am just wondering if anybody has any experience with one like it and if they had a good experience with it. I've read of some not keeping the temperature well, so a review on this one would be very much appreciated.
