Attention! Be careful!

     Today there are lots of “fly by night” companies offering cheap products of poor quality. Poor quality results from use of low grade and upgraded chips.

      That is why many people come across the situation when presented custom flash-drive becomes just a reminder of some event. Such flash drives stops working in a week or its performance leaves much to be desired. Here are some indications of bad performance:

  • Loaded data is not kept on the flash drive or kept irregularly;

  • The PC does not identify the device;

  • Working capacity is up to 8 times smaller than specified;

  • Low read and write speed.

     All these indicators result from poor-quality chips used in the production of flash drives. Flash drive suppliers and sellers rush to diminish cost and make the production cost effective buying B and C Grade chips. As a result, the customer formally gets worthy products of real poor quality.

     In consequence, all your efforts to promote your company may be brought to nought. Moreover, besides wasting time and money, you may undermine your image.

     The quality of any flash drive chip is easy to check. You should just carefully open the casing and pay attention to the label, build quality, and the casing material.

     Another problem for the customers is the contradiction between specified and working capacity. Some companies sell upgraded chips to diminish own costs. So 2GB chips are detected like 8 or 16GB ones. Practically, it’s just a consumer fraud.

     This information is just a brief flash drive market review, or the review of chips quality which we know from our close cooperation with dozens of Chinese flash manufacturers.

    Long negotiations, tests, evaluation of proposals and opportunities, lots of trips to Chinese factories (Shenzhen, China) resulted in our offer:
