Sitting at a desk all day can be pretty hard on your neck at times. Your muscles start to ache from craning you head this way and that. While you could go and get a massage, chances are you would have to spend more time at your desk job to make up for the money you lost.
There are a lot of really awesome massage chairs that can work wonders for your back, but not many that have a good portion dedicated to your neck. Panasonic has created the Neck Refre Massager that focuses on the two giant wads of muscle on either side of your spine beneath your hairline and above your shoulder blades. The low frequency waves that it produces has classified it as an actual medical treatment. As it is cordless and battery powered, it makes for very little fuss and is easy to carry around. Being equipped with three different 15-minute courses to choose from, you can find a setting that works best to your specific needs. It costs about $87, and comes with the choice between green, pink, or silver accents.

It's a little strange that relaxation tools like these are so popular and prevalent in Asia but they've never caught on in the West on a large scale, as if we just don't want to be relaxed by a machine.
