Well-designed and comfortable
This is my go-to neck massage tool.  Back in the 1970s I purchased the forerunner of all of today's bumpy massage balls called "Goosebumps."  Up until now that has been my favorite.  This product has now taken that spot.  While lying on this under my neck, the firmness and size of the peanut perfectly allows the weight of my head to put enough pressure on the area without manipulating the tool in any other way.  This allows for relaxing the muscles and passively letting the peanut do the work.<br /><br />Secondly -- and very important to me -- I have a very nice firm exercise mat that I would not use spikier balls on because I don't want to damage or weaken the artificial leather surface.  The nodes on this product, though firm, have a very slight give and are rounded rather than pointed.  The mat's surface provides perfect support for the peanut, and with regular use this tool has greatly helped reduce the burning pain in my neck that is a result of irritated of irritated nerves.
