LingGan's collection of cutting tools was unimpressive to me, a novice in the world of industrial and scientific equipment. Like blunt blades, their instruments are unable to slash through the opposition. Moreover, I had a hard time finding what I needed on their website because of how complicated it was to use. The customer care I received from them left me feeling unimportant and unappreciated. In general, I would not suggest LingGan to anyone looking for cutting instruments or power tool components.
