We may have experienced the functioning of a Home elevator at commercial buildings and might have experienced a comfortable feeling of shopping or the purpose for which we have gone out. But the elevators that are installed in the commercial building may not be as it is suitable for the residential buildings. If the same product with the same quality is provided for home purposes then we might not feel it as comfortable as we have experienced in the public building. The reason is that the residential building is not the same as the commercial building. In the commercial building, the expectation of the customer is only to make it easy for us to travel between the floors without climbing the staircases.
