I'm happy when I see this product before 4.00 per bag. My local pool shop is selling them on sale for 7.99. My water quality is within range, so it works and was a value when I purchased it.

Price is $3.75/pound - best at Leslie's in the wintertime is $5.00/pound. Leslie's is 73% cal-hypo and this is 68% so overall still a better price. It came fast, carrier chosen is late 50% of the time. On a hunch I weight the 12 bags, which came in a box and protected it well. Only 4 of them were a full pound, the rest were less than a pound - as much as an ounce. I need to repeat on my Leslie's stock and see if this is just normal variation or another way they're getting the price down. I've used this brand before - I have no way to test the promised concentration - it seems to work as well as any other.

Best price I’ve found on shock.

I picked up this pool shock specifically to keep on hand for emergency situations rather than for pool maintenance. My goal was to have a reliable, long‑lasting sanitizer I could mix with water if needed, and this product fits that purpose well so far. The individually packaged 1‑pound bags make storage simple, and the high concentration means a little goes a long way. It seems durable and stable enough to keep on the shelf until I need it, which is exactly what I was looking for. Since I’m not using it in a pool, I can’t speak to its performance there, but as an emergency‑preparedness item, it’s been a solid addition. I’m giving it four stars mainly because I haven’t had to rely on it in a real emergency yet, so long‑term effectiveness is still something I can’t fully judge. Overall, it’s a practical product to have on hand, and it gives me some peace of mind knowing I have another option if I ever need to sanitize water quickly.
