Does anyone have any experience of these? I'm officially diagnosed with ADHD and self-diagnosed with autism. I have a really stressful period coming up where I'm going to be really busy, and often over stimulated from being in crowds whilst working as a self employed person, with desperate need for good income but no guarantee of getting it. Sorry, that's really vague so as not to be outing. My thoughts are that they could be really soothing, especially during a period where I have to drive a long way and be away from home for a long weekend for the first time in 3 years.
My questions are: do you get what you pay for, as in is there a clear difference between getting the cheapest one I can find or paying a bit more? Are they actually soothing/calming? How do you decide what weight to go for?
