This shock works as well or better than any of the box store products. It dissolves quickly after applied and dose not leave any residual. I still struggle with the ridiculous cost of all these pool chemicals. Every supplier doubled there prices in 2020 because of the big fire and high demand from all the new pool owners. 3 years later and they haven't returned production to it's pre 2020 amount? Definitely ripping the consumer off!

Out of all the different brands of shock I’ve bought, this is my favorite to get. It seems to be he most efficient when it comes to clarity of the after. Other cheap chemical brands make bubbles in the water. Others shock bag brands also leave a white dust as you pour them out, this doesn’t do that at all.

Pill owners know the cost of chemicals can be high at local pool stores. This is a good product and at an excellent price. Depending on your pool size, water condition and region, there's enough for the pool season and next. Quick dessolve is best to avoid staining and bleaching of liners.

Good value when on sale. Works well!

Only has 1 of 4 ingredients as comparison to a super shock additive

Best shock & best price. Cleared my pool in less than 48 hrs. Great Job

Works the same as the pool supply stores at 1/2 the price.

Love this product

I have been using this for years. It works better than any other brands that I have used. The price is a great value. I highly recommend trying it.

I got this for like $51. The price is usually higher than this so it was a purchase I just couldn't refuse.
