The Summerbuddy Pool Closing Ball is a lifesaver for winter prep. Toss it in and forget it — no heavy lifting, no complicated setup, just simple protection that actually works. My pool came through the winter clean, clear, and hassle-free. It’s durable, easy to use, and way cheaper than dealing with green water and endless chemicals in the spring. Honestly, this little ball took a big headache off my shoulders. Total must-have for closing your pool the right way!

I buy one of these pool closing balls every year when we close our pool. They help keep the water clarity clear through the winter. It is super easy to use and the directions are clear. Good value for your money.

So easy to use- pool opening so much easier since we found this product. Water is much clearer in the spring and chemicals are easier to balance.

Will have to see how long this will last in my 26k gallon pool. Just dropped 2 of these in. Just can't trust 1 ball although description says it's good for 27k gallon pool. Very easy to use.

Very easy to use, just toss it in the pool right before closing it for the winter. So much easier and healthier in the long run since it doesn’t take as much shock and such upon reopening your pool in spring! I also feel it’s better for the environment, as it allows for less chemicals to be used at the opening, which in turn saves you money!! It’s a win-win in my opinion!

I purchased this for my pool every year when we’re closing it up for the winter. As I use a closing kit, I really probably don’t need this, but I throw it in as an extra precaution to help ease the opening of our pool in the spring. So far every year it’s worked wonderfully and the water is always crystal clear.

So far working great. No pump or anything running sense September 1. Water still clear and smells good. Not my first time buying this. It’s a good product.
