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

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.

Dollar for dollar and pound for pound I have found this to be the best shock available. Dissolves well and works great year round.

This shock works good and it is very economical which is why I have been using it for about 4 years at least. I always look for it at Sams and try to stock up for the year because they do run out fairly early in the swimming season.

Member’s Mark is the best shock I have found. Availability is not so good . I like the other MM pool products and can never find them all simultaneously.

Works well and does dissolve very quickly, but doesn’t last long and I am finding that I’m having to use 2 bags 2-3 times per week in just a 15 gal pool.

One of the major benefits of this is that it dissolves instantly. Even some of the big name shock sits on the bottom until you brush it. Excellent product at a good price.

The shock did not perform as expected. We’ve never had this happen before when using this product. Very disappointed. The shock must be old or the company used weaker products.

For the last 20 years I have been using shock from the local chain pool store and home improvement centers, What a difference this has made with the water quality of our pool. This is my new go to shock. We are on well water in North Texas

I picked this up in store for my vinyl-lined in-ground pool. It was less expensive than other shock I had found, but it worked just as well as any other I've used.
