They have even been redesigned to do all sorts of things, like light up, or resemble martial arts weapons.
While they have totally been praised for helping people focus, others say that they could pose health risks when it comes to ~injury~.
Speaking to Kidspot, a mum was horrified at the injury her son received when an out of control spinner hit him in the eye.
“He threw the spinner up a little higher,” Molly said, “and he didn’t manage to catch the spinner but it came down and clipped the corner of his eye and crunch. He was very lucky not to lose his eyesight let alone his eyeball."

Another mother posted in a mum’s group on Facebook of the horrifying moment her daughter started choking on a bearing which came loose from a spinner that she tried to clean with her mouth.
"I heard Britton make an odd retching noise in the back seat as I was driving. Looking back in the mirror, I saw her face turning red and drool pouring from her mouth – she could utter noises but looked panicked so I immediately pulled over," Kelly Rose wrote.
"The doctor was fascinated - he’d only just learned of fidget spinners that morning when he was at the mall with his son, so it was a surprise to be faced with one in a case a few hours later. He’s also an advocate for related child safety in toys, so he took a special interest in the case."
"Kids of all ages may be getting them, but not all spinners come with age-appropriate warnings. The bushings pop out easily, so if you have young kids (under 8 years old) keep in mind that these present a potential choking hazard."
Another safety concern is for the light-up spinners, which are powered by button batteries. One toy manufacturer issued a recall when they realised how easy it would be to access the button battery, which poses a potential choking and burns hazard.
Stay safe with the latest toy craze by making sure only children old enough to use the toys safely have access to them. It’s recommend to buy toys that don’t come apart easily to reduce the risk of a choking hazard.
