Horrible! The old saying, you get what you pay for! This was almost $15 LESS than the name brand SunPurity blue square for my SunDance Spa. It arrived in a sealed plastic wrapping with a thick BLACK powder around it. Was this so OLD that it's contents turned black/disintegrated? I set up return & quickly CANCELLED my repeat "Subscribe & Save" membership delivery & ordered the Original NAME BRAND SunPurity.

Between this and the Clearview bulb, no need for chemicals in your hot tub! No smells and clear water

These discs are great and you use way less chemicals. Hot tub stays sanitized all winter long with only being shocked 1 time

This is the second time I purchased this product. It does work but not for 4 months. I only have a 250, gallon spa water which is less than the manufactures claim to help clarify.

I have used this product for about 10 years. It enhances the water quality, reduces chemical use , and last for several months before needing to be replaced. It has made it easier to maintain clear water and the convenience of it being delivered to your door it fantastic.

This replacement spa sanitizer is economical and appeared to have a greater silver content than the original (the active ingredient). Will be buying these regularly.

Placed in hot tub and water is clear and nice now! Good price. Others I looked at were way overpriced. This brand is for 4 months but can buy two of these (8 months) and still better deal than the expensive 6 month brands.
