Most people think that the key to buying data line is the price, in fact, this is the biggest misunderstanding. Just mentioned, the data line according to the manufacturers to sub-sub-domestic brands and domestic-made without a license, there are no domestic brand-name non-brand, the quality is really poor, there is a root 3 is a bad, confused customers keep Suspect your computer water
Flat bad, ye installed on the computer does not recognize ah! So to distinguish the quality of products and find a good seller is the key factor.
More powerful sales force is generally the product quality assurance, because they do not want to sell the data line has been returned and exchange it, do not say round-trip postage, even if time and energy also consume a lot. As a result, gold sellers will work with reputable and reputable manufacturers, which typically have a failure rate of 1%, while some non-performing manufacturers have a failure rate of 30%. This is why the same model features data cable price difference of 2 times worse, for example: DKU-2 data cable sold 12 yuan, sell 25 yuan, courier is 15 yuan, if 12 yuan is Poor quality line, can not be used normally, you have to call the seller consulted, a phone at least 10 minutes (and possibly hit many times), a conservative estimate of 5 yuan phone bill, eventually under the guidance of the seller's phone, or not normal Use, resulting in replacement, then you have to at least 15 yuan more mailing costs (at least you send back the money you dig it, a line was only 12 yuan, the seller will not be able to paste 15 yuan courier to you , Get the buyer's replacement courier fees have to count on your head, that is 30 yuan), so that the total price is not much higher than 25 yuan that line. This is just a monetary loss, in case you play this line took 3 nights, then the loss of time is even more immeasurable. More unlucky is the data line in exchange for the normal or not, I think when your mood .......
Even the same data line, buyers at different vendors enjoy the price and service are different, the high prices may come with free testing, technical advice, website download, free replacement, and guide the installation of a range of services. Why the price of coffee bar shop than the high? This is the same reason that services and grades are different.
Therefore, we always firmly believe that a price of a stock, the data line is not simply the price of the line, as well as technical and after-sales service content in it, cheap and service is always impossible to maintain a balance.
