The WF Series juicer is an economy, chinese made, copy of popular juicers such as the Santos, Nutrifaster, and Ruby juice extractors. You will find the unit very similar in form and function however, as the price difference shows, there is a quality difference. We will always recommend the Santos or Nutrifaster if you can afford it. If those units are out of budget, this is the alternative. Typically these units will be replaced within 3-5 years while the higher end units will last for many more.
