A decent heater for the money but they do not last

General These "Theo" heaters do the trick but only for a short time. 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
