Hi, I am David Andres, I am a researcher & business. I run a business where I sell different types of blender machines and its related tools. Because of my business, I have to face so many clients of these blender machines and tools users. I saw many of them face difficulties with installation, maintenance, not getting the exact amount of service, or buying the wrong one. All those problems they face because of their lack of knowledge about blenders and its accessories.
