Demand for Asustek Computer's latest smartphone series products, including the entry-level ZenFone 3 (ZF3), mid-range ZF3 Ultra, and high-end ZF3 Deluxe, in the US market has been higher than expected since the vendor began taking pre-orders at the end of September, according to a Chinese-language Economic Daily News (EDN) report.

The first batch of ZF3 smartphones shipped to the US on October 12 have completely sold out, said the paper, adding that subscribers will wait for the new arrivals until October 26.

Asustek has been particularly encouraged by strong sales of its high-priced ZF3 Deluxe family products, said the paper, adding that the ZF3 Deluxe series are available in three variants: 5.5-inch ZF3 Deluxe priced at US$399, 5.7-inch ZF3 Deluxe at US$499 and 5.7-inch ZF3 Deluxe Special Edition at US$799.

Asustek has been marketing its ZF3 series products in Taiwan, Thailand, Malaysia, the Philippines, India and Indonesia.
