At present, there are several companies producing lasers, including BOBLASER Company, lvyilaser Company, CNI Company, and Viasho Company. Now lvyilaser Company occupies the largest market share in China, whereas the largest company is CNI and its products are of high quality. BOBLASER Company is mainly engaged in export market, and it focuses little on Chinese market. Viasho Company has the longest history. All in all, these four companies are highly recommended!
