Great stuff!

Have been using the Frog system for over twenty years and love it. The ease of the application is a great factor in the fact we continue to use it.

SpaDepot is great and love the $1 deals buuutt...

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.
