I have had the 100w 150w 250w and 400w. I am currently using the 400w in my salt mix tank. I do not use it for long periods of time. Just turn it on a day before a WC to get the ASW up to temp. This is why it has lasted longer than others. Liked about it Shatterproof fully submersible fairly accurate thermostat. Didn't like They do not last Overall rating:   2.5 Overall satisfaction:   3.0 Would consider buying it again:   2.0 By ckusnierek Jun 18, 2009   Ask ckusnierek a question about this item.
