The SpinPro Trimmer has a 1 year warranty, dishwasher proof parts, and stainless steel Japanese components. Trim up to 2 ounces of wet plant material in 5 minutes. Save a great amount of time during your trimming and harvesting process. This is not a cheap Chinese knock-off like many of the other bowl trimmers available for sale. Other bowl trimmers may be made with harmful chemicals in their rubber.
