It is a fun thing but I don't see it becoming a necessity for me. I am used to the feeling of my arm being cuffed by it now and have answered some questions about my sleep and feel mostly at ease and normal. I can't imagine it lasting the life of a wristwatch as it corrodes at the charging brass plates. The band also seems easily damaged and not so tough as I believed it to be. I purchased it online thru a email sale. All in all I am glad I got it and recommend it. It is a little wide and feels abnormal at first. The stiff band is not the best for it I feel. I may only wear it when working out or working hard and then charge/drawer it for the next time.
