Tesla missed expectations for third-quarter deliveries on Wednesday, hurt by stiff competition from rivals in China and Europe, sending shares of the world's most valuable automaker down 3%. The electric vehicles maker handed over 462,890 vehicles in the three months to 30 September up 6.4% from the preceding quarter. Wall Street on average had expected the Elon Musk-led company to deliver 469,828 vehicles, according to 12 analysts polled by LSEG. The company has to deliver a record 516,344 vehicles in the fourth quarter to meet last year's delivery figure of 1.81m units. A shortfall could result in Tesla recording its first annual drop in deliveries.

Neato Robotics is shutting down as the company hasn't reached its "self-defined economic goals" for years, parent company Vorwerk Group tells TechHive. The firm's sales haven't met expectations, in other words. Vorwerk is promising cloud and repair support to Neato customers for "at least" five years, so your robovac should continue to run for a while longer. The move will affect 98 jobs, Vorwerk says. Users started worrying weeks ago, when users noticed a broken customer sign-in page.

Getting the right balance between golden liquid and a foamy head is tricky business when it comes to pulling the perfect pint of beer.

When Karma was unveiled last month, there were two main takeaways. First was the lack of much-expected "follow me" features; second was the inclusion of a (not-expected) handheld stabilizer, turning Karma into a "kit." GoPro CEO Nick Woodman would declare Karma to be "much more than a drone," pitching it as a complete video stabilization system -- one that can be worn, held and flown. The big question was, would that be enough for buyers to overlook what appeared to be a pared feature set on the drone itself? As a drone on its own, GoPro's Karma lacks a lot of features offered on rival devices, while the battery life is toward the low-end of acceptable. The big appeal here is the ease of use and overall versatility. If you're invested in the GoPro ecosystem, Karma makes a lot of sense. More serious drone enthusiasts will want to look elsewhere. At $799 (if you "bring your own camera"), and $999/$1,099 if you want to include a Hero5 Session or Black, Karma is priced aggressively, undercutting DJI's Phantom 4 if you factor in the cost of the handheld stabilizer (DJI's cheapest equivalent costs an extra $300).
