Personally, according to the plug-in machines currently on the market, Panasonic in Japan is the best, but the price is too high. Domestic plug-in equipment manufacturers mainly include Xinzegu, Zhonghexu, Huawei, Zheng Ke and Norbert Electromechanical, which has just been listed. Our company has recently bought Panasonic, Zhonghexu and Norbert NB- 168 last year. In all respects, Norbert NB-65438.
