Helpful for Eye Strain
This thing is pretty darn cool!  It really looks like something you'd see in a futuristic movie.  The eye massager is a pretty large size, so it should be able to fit around any size head.  I like that there is an option to use a USB cord to power this device, instead of only being able to use batteries.  This eye massager has done a pretty decent job of relieving minor headaches cause by eye strain thus far, but I haven't had much luck once a headache gets really bad.  I am still playing with different settings though, and will update once I've found a good one for major eye strain.  This is definitely a cool device.
