Why the fidget spinner is friction disadvantage?

Fidget spinners can experience friction disadvantages primarily due to the materials used in their construction and the design of their bearings. If the bearings are not properly lubricated or are made from lower-quality materials, they can create excessive friction, reducing spin time and efficiency. Additionally, dirt and debris can accumulate in the bearings, further increasing friction and hindering performance. As a result, the spinner may not spin as smoothly or for as long as intended.
