Query: Life-changing!

This changed our lives. Without exaggeration - it was a blessing. It is so easy to set up by the care-giver, and then the family member can get their medication on time and independently without having to ask for help several times a day (and during the night). It's very empowering and completely safe. I wish we'd purchased this years ago. I let the cost scare me away for a couple of years, but it's worth every penny. Sadly, we only got to use ours for six weeks. It is for sale now.
