An instruction manual was for sale for $250 (R6 535). Musk and the Boring Company team only offered 20,000 flamethrowers - all 20,000 of which sold out within four days of being offered on the website.
The Boring Company sold the devices to help raise money to fund development of its tunnelling machines and for testing.
But The Boring Company had an even bigger surprise for their customers, and this was to hold a special flamethrower pick up party on June 9 in Los Angeles so that the first thousand flamethrowers could be personally distributed, something that has gone down as a treat with buyers.
It's unclear when the next batch of flamethrowers will ship to customers.
The billionaire posted a warning to Twitter Saturday: "Please use as directed to avoid unintentionally burning things down".
It continued: "I will not use this in a house, I will not point this at my spouse, I will not use this in an unsafe way, The best use is créme brulee".
Right now, The Boring Company's website says they are sold out of "not a flamethrower", but you may want to check back soon. While we've spent the past few months wondering what kind of good would come from owning such a device, today the news comes down that the first 1,000 flamethrowers have been picked up. Instead, they work more like large propane blowtorches.
We all remember the controversy that surrounded the flamethrowers announced by Elon Musk.
Ahead of the original launch of the gun, he said: 'When the zombie apocalypse happens, you'll be glad you bought a flamethrower.
Musks' official Twitter account and the account for the Boring Company together tweeted a total of 16 photos from the event, mostly of their customers testing out the new product. It has been the most dramatic fundraising technique for The Boring Company by Elon Musk to date and it met its fair share of resistance as well.
