There is something so satisfying about mindless manipulation of toys that fit in your hand. We all do it; it could be rubber bands or those squishy tension relieving balls. For some, it helps them to focus. In fact, many people with ADHD use it to remain focused. High-level thinkers, especially engineering students claim that it helps them. Zorbitz makes no such claims, they just wanted to produce a fun, fidget toy that moves easily and makes an interesting variety of shapes. According to our testers: Mission Accomplished. Twiddle provides a very satisfying manipulative experience. It twists and turns and does, in fact, produce some very interesting shapes. If you combine Twiddle with others that have different colors, the permutations take on a whole different look. Testers felt that Twiddle was sturdy and well made and, for the price, would make a great stocking stuffer for any age.
