Asian Tech Press (Jan 5) -- Tesla's official website in China showed on Wednesday that its Cybertruck-shaped whistle is out of stock.

The whistle named "Cyberwhistle" is based on the design of Tesla's much-awaited electric truck Cybertruck, previously available for a limited time in the U.S. for $50 (about 318 yuan).

The limited-edition item is now available in China, where it is priced at 350 yuan ($55), a pricing that is over 30 yuan more expensive than the overseas version, but it is still being snapped up quickly.
