Query: Waste of money

I read the mixed reviews on this product but decided to go ahead and try it for myself. I actually hate it and am mad I wasted my money.First, the blue foam part is scratchy itchy material that is not comfortable at all.Second, the small white piece that curves under your neck is not stable at all, so your head tilts from side to side unless you want to not relax and try to balance.Lastly, it just did not feel like a drastic enough curve for my neck although it appears that it is in the photo, most of that curve is the piece that wraps up around your head.Bottom line is, it might work well for some and not for others and you'll have to decide if you want to spend the money to find out if it does or not.
