Quality Assurance at One River Electronics Ltd. provides a complex inspection procedure that meets the highest Quality Standards. Our prime goal is to 
reduce counterfeit/substandard components from entering the procurement process in its entirety.
For each quotation, there are at least two or more reliable suppliers,which can protect our customers' benefit.
Before delivery, we will recheck all the details of the parts, including packaging, marking, pins, and quantity, to makesure all the parts are in good quality 
conditions.
All of this, combined with our stringent anti-counterfeiting policies, allows us to offer our 1-year quality guarantee, should your components fail to meet 
manufacturer's standards within 1 year of purchase.
