I ordered this replacement bulb on March 22, 2009 and today's date is July 27, 2009 and it burned out 2 days ago! That's only 4 months and at $21.99 for a replacement bulb it should last allot longer than that!! I, too, noticed that it's a close out item and that no returns will be honored.....therefore I think I'll go to my local Wal Mart and buy another brand bulb and if necessary spend a few dollars more and get another brand bug zapper....one that I can trust!! I bought the Flowtron one only 1 year ago....had to replace the bulb approximately 8 months later....what a waste of money! I gave it two stars because while it did work...it did a good job. No better job than any other unit, however.
