Would be great, with just a few changes
Overall, this appears to be a good product.  It's not fool-proof, but I wanted to present my mom with something that would be as similar as possible to the pillbox she was using, but would remind her which pills to take and when, as she had double-dosed and missed doses. As others have noted, there's nothing in the way of instructions, which you have to look up online.  I had no trouble setting the alarms initially, but ended up messing them up while trying to demonstrate the alarm to my 94-year-old mom who has dementia.  The arrow, which indicates which side of the pillbox the alarm is for, is very tiny and difficult for my mom to see.  (Actually, I didn't see the arrow either at first, hence the reason I messed up the alarm and assigned the a.m. alarm to the p.m. boxes and vice versa.) She wants to know which side of the box her next pills are going to be on, so this is a problem.  A bigger arrow and a lighted LED screen would have been helpful.  Also, it would have been nice if one side of the boxes had some kind of marker to differentiate them.  I'm going to get some little dot stickers or something to put on her p.m. boxes so she can easily see which ones are which.  We've only had this pillbox for less than a week, but I think she'll get the hang of it eventually.  She gets her days and nights mixed up pretty often and calls me to tell me that the alarm didn't go off (at 7:30 p.m.--because it's supposed to go off at 7:30 a.m.), but other than that, she seems to understand that she has to hit the "Next Alert" button to turn off the alarm.  With a few improvements, this would be a 5-star product.
