Bought the product a few weeks back and has been using it non-stop. I'm a gym goer so often have upper back and shoulder and neck muscle restrains due to heavy lifting. The massager really helps targetting those areas. I found that it isn't only just a shoulder and neck massager but also good for all areas. I like the heating function - really calming and soothing. The product also has a car plug which is SO convenient and useful because i find long drive is a killer on my top shoulder too. The only downside of it is the plugs are not connected properly and as i move they often fall out. Hopefully this will be fixed.
