Fair price. Good delivery time.

Awesome company and great customer support!

Really great alternative to Clorox tablets in the tnk which can damage tnk parts and break down rubber gaskets. Fluidmaster tech service at their headquarters telephone number was fabulous, courteous and knowledgeable. Can't say enough good things about this product.

Love the item and the work.

The refills were delivered well wrapped, with plastic bags in which to dispose of the used cartridges.
