Easy
I’ve been using this system in my hot tub now for five years. It keeps the water fresh and clean and your skin feels fine when you come out. Often we don’t even feel like we need to shower when we get out of the hot tub. It’s also very convenient.

Great! But dont throw away the used ones!
These are excellent as a quick and simple way to add minerals and bromine to your spa if you have the Frog system. However they are fairly expensive for the convenience. Protip! When you are done using one of the bromine cartridges, you can pop the top off (several tutorials online) and refill them with your own bromine tabs. This will save you a ton of money down the road.

Keeps my hot tub crystal clear
This keeps my hot tub crystal clear without much smell and is pretty easy on the skin. This pack last 4 months and the water is still crystal clear. I will drain it and change it out anyway as that seems long enough between changes, but I couldn't ask for it to work better.

Good but overpricedc
Product is good but overpriced. Due to delay in delivery we had to find this poduct at a local pool store. The price was 40% lower for the green bromium cartridge which contain 25% more bromium. The yellow cartridge contains 150g and the green 200g!!! The blue cartridge was almost 50% cheaper.... Bottom line buying at a local store would have us save 100$. Never again!!!
