I have been really happy with this posture corrector, mostly because it just works.
Having going through physical therapy for my neck and currently going through my shoulders, I now get the importance of addressing these issues. Long commutes to/from work and sitting at a desk job are just brutal on the body. Combine that with exercise routines and bad posture, the body can only take so much.
This I just put on, hit a button, wait for it to vibrate and I know it's good to go. The first time is a little strange, but once you get used to it, it's super easy. The battery lasts a long time and frankly keeping good position when you are not used to it is not easy, but totally worth it. Not a product to wait on; if you don't have you health you don't have anything.
