From what marineland emailed me about the faulty elements they used I'd say inevitable . They will still take them in . I bought a used tank last month from Craigslist and it came with a 100 watt stealth heater , I emailed marineland and said I would pay for the extra for a 300 watt ...... They sent it out free of charge in exchange for the stealth !
Oooh, I think I'll have to get on that. Thank you for telling me!
