Looked at each electricity supplier, DT990 PRO prices are above 1200, check the next Aunt, found before the Central Asia to 999 yuan, but when will the price have to have, want to enter the big ears of the heart is not Live, continue to look for, find Aunt Zhang on the new egg this big-eared push, immediately register a single order, but hesitant to pay, because to see comments that the new egg is long after waiting for an order, they gave up from the new egg buy. Later, in the United Kingdom, the Amazon found that the DT990 PRO was only 114 pounds, and it was calculated to be as low as 950.
