Because the R&D investment behind the weighted stair climber is very large, and it has exceeded about 5 million yuan at present, how can such a product that focuses on R&D investment not become popular? For example, my country’s mobile phone industries such as Huawei, Lenovo, and ZTE have invested a lot of research and development efforts. Moreover, for the logistics industry, the stair climber is a new thing. From the beginning, we realized that popularization must take a certain process, so we must pay attention to this stage of research and development. In the past two years, my country's demand for the handling of large household appliances, heavy objects, and bulk commodities has soared, which has a lot to do with the development of e-commerce. In the past, people liked to go shopping and buy in physical stores. Now online shopping has become the main way of shopping. From a piece of socks to heavy items such as refrigerators and electric motorcycles, you can buy them online. Therefore, the logistics industry has naturally emerged, and the demand is particularly large.
