What the new weapons are good for against tension

Massage pistols:-

What can they do, what do they cost, when do they hurt? We did the test.

Back pain “shoot away” at the push of a button: massage pistols are currently conquering the European market. How do they do in practice?

They hum, knock, vibrate, and shake. They are now available in all colors and shapes and from different manufacturers; they can be dirt cheap or incredibly expensive: massage pistols for troubled office workers. A trend in the USA for a long time, the devices are conquering the European market.

Manufacturers target highly motivated but motionless, long-term seats at the desk with uncomfortable neck tension, shoulder, and back pain. The devices, which cost between 60 and 600 euros, promise quick and effective remedies at the push of a button.

Because the massage pistols are becoming more and more popular, more and more suppliers are appearing – but sometimes with very dubious devices, which on closer inspection turn out to be cheap and imperfect copies of the branded products. The dealers, mostly from Asia, lure at low prices. The selection at the online retailer Amazon is now gigantic – who should keep an overview? read more

Why robots still haven’t arrived in everyday life

They’re bland, quiet, and at the pushiest when they’re wrestling with the edge of a carpet or getting tangled in power cords. Vacuum cleaning robots are used in many households.

Roomba is something like the iPhone of the industry: Introduced in 2002, the round robot was not the first of its kind. But it was the first to prevail. The Intelligent FloorVac for $ 200 defined the product category. To this day, Roomba defends its place despite many imitators. More than 20 million units have been sold, and there is no more successful home service robot.

Clara Vu played a significant part in this success. Her first job in 1998 after studying mathematics at Yale was to write the code that controlled Roomba. Its manufacturer iRobot, a start-up of three graduates from MIT’s elite university in Boston, was able to go public thanks to its success. Vu had enough and moved on. read more
