They better. They claim a 2 year warranty I believe, on the tank and motors. "Within two years from the date of original purchase, Marineland Aquarium Products will repair or replace, at its option, any Eclipse System which is deemed defective in workmanship or materials.
This aquarium is under warranty against leaks or cracks due to defects in material or workmanship. If this aquarium is found defective--and has not been modified, damaged, or misused--call Marineland Aquarium Products at 800-322-1266 for a replacement (proof of date of purchase must be provided).
This warranty is void if the aquarium is not placed on a flat, level surface designed to support this size aquarium or if the aquarium is moved when it is not completely empty or if it is used for other than its intended purpose. Warranty does not cover loss of fish, personal injury, property loss, or damage arising from use of the aquarium."
That being said, I think every company experiences some type of production problems, eventually. It's nice to see that they're willing to accommodate their customers when that happens though.
