    Easiest Way to Care for Your Hot Tub
  

*by K***5 on Reviewed in the United States on November 22, 2022*

The Frog Ease system works and is is easy to deal with. I usually change these out at the first of each month and change out the top part of the system every quarter when I drain and refill the tub. It is an easy system to use and the subscription option keeps me from having to think about it.

    Easy to use chemical dispenser
  

*by C***2 on Reviewed in the United States on May 28, 2022*

This product is great, I've been using it for 2 yrs now. It came with my hot tub package originally.The only problem I've had is twisting the top on and off. Maybe because I have long nails!I only have to change this every 3 - 4 mos. instead of every day or week.

    Easy worry free use
  

*by P***M on Reviewed in the United States on November 3, 2022*

Love that I can just drop this in after I set it where I want and it takes the work out of sanitizing the spa. Water stays clean and chlorinated. When it flips you know you need to replace the cartridge.
