According to the manufacturer, almost every part is replaceable. Interview with representative
AECT has products manufactured in 1985 that are still in use. AECT representative states that if they are treated well, there is no reason for them to stop working. Most of the parts are replaceable, and the replaceable liners in the product prevent dirt from metal corrosion, the main reason for product deterioration. Since each user is required to be trained for the product, there is a 6-month warranty. No disposal information is available. Interview with representative
