These cartridges are the same fit and style of the name brand cartridges. Easy to use and adjust to the setting you want it to be. Keep my spa clear and chlorinated. Good value for the money.

Doesn't preform like Frogease at all. Chlorine levels are constantly low when using this product. Always have to add separate chlorine granuals to maintain a consistent level.

These work just like the official branded ones that cost a lot more. However they do seem to get used up a little quicker. The main ones I get 3-4 weeks from with my hot tub size and these are no more than 3 weeks. The cost benefit is still there because they are so much less. I also like that they are not shrink wrapped which makes it easier to take out of the package. Each one is in its own zip bag. The official ones are shrink wrapped and a pain to open. They fit inside the spa frog easily and so far no issues. Would get these again.

I tried this because it is so much less expensive than the name brand. It does work as intended, but it only lasts about half as long as a name brand cartridge. So in the long run it doesn't save money. May even cost you more and has to be monitored more closely. Switched back to name brand.

Caused my hot tub to foam up. Extremely HIGH CHLORINE SMELL. My smart chlor testing strips were off the chart. I do not recommend the purchasing of this item.
