The material and design of the bearings affects the rotational time, the type of vibration and noise, creating a unique touch feedback. Spinner is being advertised as a means of helping people who have problems with concentration or anxiety (eg, ADHD, autism or anxiety disorder), acting as a trigger for nervous energy or stress. Experts have been divided into evaluations of the benefits of a health spiner: some believe that it can help in these cases, others deny this opportunity and believe that the toy is more distracting than helping to concentrate.

As a result, spiners were banned in several US schools based on the fact that toys distract children from learning, but in some schools they are used only to help students concentrate.
