Shock works great. Bags seem bigger than average which is a plus. I will definitely purchase again.

Great product, was missing test strips. The box was unopened so it must have been left out during production.

Effective for shocking swimming pool. Clear water after shocking my pool after heavy rain storms and mud/dirt getting into pool.

This is a wonderful product! Very helpful after several weeks of rain, it cleared the pool up very quickly.

Ordered online and received the shock stabilizer quicker than I expected. Works well, and is reasonably priced.

It works as good as other brands out there, it just cost lot less. I am very satisfied with this product, will purchase again.

This shock is easily dissolved in the pool and is the only one I use now as a result. It is also priced right.

So far the best pool shock available anywhere. I started to use it weekly and the pool stays clear and clean looking.

This product is wonderful but the price is outrageous! But, for the fact I HAVE to have it for my pool…I’d skip it!!

It is perfect and does exactly what it is supposed to do. I use two lbs. of shock a week 23 thousand gallon pool
