The price of these Serene Frog Bromine cartridges have more than doubled since the onset of COVID. Not SpaDepot's fault so 5-stars for their prompt delivery and customer service. One suggestion would be extending the $1 offers when someone spends 2x etc...abive the offer threshold. For me that would have meant two $1 offers.
Thanks for taking the time to review Spa Frog Serene Bromine Cartridge. We're always looking for ways to enhance customer experience and will definitely take your suggestion into consideration for our $1 offers!

Good product
I have been using the Spa Frog Bromine cartridge for 10 years. It has been a consistently good product and has kept my hot tub in chemical balance. I highly recommend the product. The price has risen dramatically, but name something that hasn't.
