Easy to use and adjust to the setting you want it to be. Keep my spa clear and chlorinated. Good value for the money. ### ⭐ Review *by M***N on 25 February 2026* 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. ### ⭐⭐⭐⭐ Review *by R***0 on 17 February 2026* 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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/807795663-hot-tub-in-line-smartchlor-replacement-cartridges-3pack](https://www.desertcart.ie/products/807795663-hot-tub-in-line-smartchlor-replacement-cartridges-3pack) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-05-25*
