Is it reasonable for the property to require the designated manufacturer to replace the new elevator in the community?

The property has no right to ask the owner to buy the designated manufacturer, but it can communicate and negotiate with the local market supervision bureau. The purpose of designating manufacturers is nothing more than profit. The reason for appointing the manufacturer will definitely be the quality of the elevator. However, elevators that can be sold have factory certificates recognized by the state. Of course, it is undeniable that the quality of use is indeed uneven, but you can choose a first-line brand to buy. Don't listen to the property. He wants to specify and let him pay.
