Last but not least, I never said they were bad although I will admit I didn't go out of my way to suggest they weren't either. My opinion is they fail far to quickly and believe you are the exception and not the norm. I believe further that the manufacturers know and acknowledge by their warranties alone that they are far less likely to last with 6 months being the longest I've seen. One manufacturer even covers their glass heater for 12 and titanium for 6, seems straightforth enough for me.
