This is a great product for sanitizing an RV fresh water system when compared to chlorine. Works well and good price when buying in bulk.
Had to contact company via email to find out where my shipment was. Label was created but never delivered to USPS until after my email days later. A bit concerning that there is no phone number to call for help. In the end, I received my shipment (later than expected) and I am happy with the product.
