Probably have used it for a total of 10 hours and still hasnt given me any signs of low battery. I love it this night shirt. gm6534 I like that it has hooks so I can adjust the size, and it is hardly noticeable under clothing. I will use and report back on accuracy but it is supposed to be really accurate, so I look forward to using it now without constant vise like head pain. gm6534 Fits 4E width in size 14, not sure 6E would work though. gm6534 These are great if you suffer from plantar fasciaitis and your Dr says NO BARE FEET. My waist is now 24. Espero que te sirva de ayuda mi opinión. gm6534 We bought the 12-18 months and they were snug. Love the case as well as carrying case for trips.
