Nice idea but not sure about the design that may be considered confusing
The design is as-pictured and one may question the graphics.  The options represented on the round magnet:  Take Pills with a green checkmark [green presumably signifying 'go'/proceed]; Pills Taken with an x over a vial of pills.  I believe that this may be confusing rather than simple and universally understood. It seems more logical, at least to me, to have the reminder Take Pills (with  a picture of the vial without an x, if using the design elements chosen by the seller) --- since a check mark signifies a task accomplished not a task yet to be addressed; pills taken perhaps reflected with the words and a visual with the x (even a red check mark might be confusing) .  This magnet graphic reminder seems over complicated and overthought to the point of confusing what should be able to be used as a simple reminder without any chance for misinterpretation of the words or graphics.  This type of visual assistance for medication should avoid any lack of clarity or chance for reasonable misinterpretation.  Pills Taken and Take Pills might have been a better option -- perhaps with a an alternative with graphics not subject to multiple interpretations.
