When researching the rear-view mirror wherein I was interested, I learned that this mirror was offered this company and a firm in Germany. I read the reviews and went ahead with the purchase. I received my mirrors (I bought two: one for each of my two bikes) in a reasonable amount of time. My first thought was "Great!" And then I found a problem: one of the mirror kits was missing the handlebar inner brace. I have contacted Sewoong International twice asking for a replacement: and have twice been ignored. So does a company which sells a commodity receive a 5 star rating for ignoring their customer? In my opinion, no. To me a 3 star rating would suggest that they at least tried to remedy the issue. That did not happen. In summary: Delivery was Good: price was good: customer service is lacking. I did ask twice for a replacement part that is a principal component of each mirror kit. Two stars.
