## Customer Reviews

### ⭐⭐⭐⭐⭐ Good Planner
*by C***C on April 21, 2025*

This planner is good for those who still like to see things on paper at a glance. I like flipping through the planner to find dates in a second instead of fumbling through my phone. I keep mine right by my landline phone.

### ⭐⭐⭐⭐ Refill your cartridges for half the price
*by N***K on January 7, 2025*

This product contains three pounds of crystals for almost the same price as individual 1.5 lb cartridges.Rather than throwing a spent cartridge away, empty, and then clean it (or put it in the dishwasher), and use a kitchen scale to refill with this product. This is enough material to refill a system twice, and a plastic cartridge can be used many times if it is opened carefully.

### ⭐ Not good at all
*by A***R on July 24, 2023*

I want to return this item but amazon & seller didn’t process the return.👎
