Well this post is not for just Smartrise but all of the majors included. All are playing the "Obsolete Game" to bill customers. Elevators used to last 50 years if maintained properly but now within very few years chips and board components are not in production anymore and the elevator companies call it obsolete and bill for upgrades and mods. Typical lifespan of an Elevator is 10 years or less anymore. Nobody stocks anything and when they can't buy it from the original manufacture again they bill customer for upgrades. Even though the part may be available somewhere else they still bill.
