Singapore's largest technology show, Comex, saw a massive turnout yesterday at the Suntec Singapore Convention and Exhibition Centre where it is being held.

The tech show, which covers 24,000 sq m across levels 3, 4 and 6 of Suntec Singapore, opened last Thursday to a good response.

But at about 4.30pm yesterday, the exhibition halls were so jam-packed that ushers had to temporarily stop people from accessing levels 4 and 6 for about 15 minutes to ease the congestion. Vendors have told The Sunday Times that the big turnout means several popular products are almost sold out.

"Our Asus Zenbook UX305 ultra-portable clamshell laptops have been flying off the shelves here and are almost out of stock," said a spokesman for Taiwanese PC maker Asus. "We sold more than double the number of laptops on Friday compared with Thursday, and are expecting even more promising numbers today."

This year's show features a new trade-in programme and a dedicated gaming area, both of which have proved popular with visitors. The trade-in programme lets visitors exchange their old or faulty gadgets for cash vouchers, which they can use towards purchasing a new item.

At the GAMEX pavilion, gamers can get to try out a demo version of the popular fighting game, Street Fighter 5, which is slated for release exclusively on the PlayStation 4 console early next year. Marketing manager Teoh Wah Keong of Sony Computer Entertainment, which runs the Street Fighter 5 booth, said: "Several thousand gamers have had a go at the game so far."

Visitors can still visit Comex today. Level 3 opens at 11am, while levels 4 and 6 open at noon. The tech show closes at 9pm.
