Google Glass, wearable smart eyewear that can shoot videos, photos and obey voice commands, is on sale in South Africa for close to double the prices charged in the U.S., according to ITWebAfrica.

In the U.S. the device being sold for $1,500. In South Africa, Google Glass cost 26,999 rand
or about $2,700.

Wearable technology took a huge step forward over the past year and shipment volumes will exceed 19 million units in 2014, more than tripling last year’s sales, according to the International Data Corporation (IDC). The global market is expected to grow to 111.9 million units in 2018.

South Africa’s Takealot.com is among the first to sell the device in South Africa, ITWebAfrica reports.

On its promotional web page, Takealot.com is marketing the sale of Google Glass in black with split style frames and edge style frames — and it claims quantities are limited.

Google introduced Glass to the world with a bang, but the company has not advertised the technology to the general public, according to Telecrunch. For most people, their only interaction with the device is with a random person wearing Google Glass.

These random people are known as Explorers by Google, and they’re Glass advocates who are helping spread the word about the new technology. Google has rules for and by these Glass wearers.

“We’re at the start of a long journey and we’re looking to our Explorers to help us develop this new technology,” Google says in the introduction to the list of do’s and donts. The Explorers themselves are developing the “protocol” for friendly adoption by the public.

Here’s an example on Google’s do’s and don’ts list for Glass. Violators risk being called a “Glasshole”:

“Don’t Be creepy or rude (aka a “Glasshole”). Respect others and if they have questions about Glass don’t get snappy. Be polite and explain what Glass does and remember, a quick demo can go a long way. In places where cell phone cameras aren’t allowed, the same rules will apply to Glass. If you’re asked to turn your phone off, turn Glass off as well. Breaking the rules or being rude will not get businesses excited about Glass and will ruin it for other Explorers.”

“Google’s challenge,” according to Telecrunch, “is not building the Glass platform, but training the general public to welcome Glass wearers into society. Glass’s future rests largely on the public’s acceptance of the technology. If, like Bluetooth headsets, it’s deemed nerdy or, worse, if Glass is lumped in with the NSA privacy scandal, the technology will be an also-ran. A lot is riding on Google Glass Explorers.”

Takealot.com started selling Google Glass in South Africa after receiving a $100-million funding boost earlier this year from Tiger Global, ITWebAfrica reports. Tiger Global manages hedge funds and private equity funds by investing in local and global public and private equity markets.
