My hearing is almost "20/20" and sometimes I can't hear it in my pocket either. I bought it at REVCO in Dayton Ohio for $12.99. It has no mfg. mark off any kind, holds my days supply of 7 sinemet, 12 parlodel,2 eldyprel, 2 symmetrel,and 3 xanax.Since I am on a 3 hour cycle, I couldn't operate without it. Hope this helps. I can snail mail you one if you wish. Storkie1@ aol.com, known off line as Don Boyer!!!!
