Zuru BunchO Water Balloons at Costco Review

When we spotted the Zuru BunchO Water Balloons at Costco we just had to try them out. The box said that it can fill and tie 100 balloons in just 60 seconds. I wasn’t too sure if they would actually work, but was willing to give them a try. I can honestly say that I am so happy we decided to buy these.

It might be one of my new favorite purchases from Costco! 


  • $19.99 USD at my Local Costco. 
  • 420 water balloons total.
  • Located in middle of store near toys. 
  • 2017 Toy of the Year Award
  • Costco item number 1506370.

Everything in the box

When you open the box, you will find the 12 different colored bunches of water balloons.

We followed the instructions on the back of the box and the balloons worked perfectly.

Filling up the Water Balloons

We first filled a large tote about halfway full with water. This helped to remove extra air from the hose and the water in the tote will allow the water balloons something to rest on when filling.

Then we connected one of the Zuru BunchO Balloons to the end of our hose. It was really easy to get on. Just a couple of turns and it was connected.

Just be careful not to touch the bunch from the balloon end, because you might accidentally knock off some of the balloons.

Next we held the water balloons right above the water in the tote and gently turned on the hose about half a turn. Slowly the water balloons filled up.

After they were done filling, we turned off the hose and then pulled up really fast and all the balloons fell off the end of the hose connected and into the water. It took a couple tries to get the hang of it. You just have to pull up really fast and they will fall off.

The first time that we filled the balloons, we didn’t fill them with enough water and they were are bit hard to break. Here is a photo of the one that didn’t have enough water.

After that we started filling them with more water and they worked much better. You want to fill them until they look similar to this red one.

Final Thoughts

I am in love with the Zuru BunchO Balloons. These make filling the water balloons so much easier. I will never go back to the old way. 

These water balloons would be great to purchase for a party or event. You could literally fill the entire pack of 420 balloons in less than 5 minutes. We just used a couple of the bunches and will be saving the rest for another time. 

Since this is a seasonal product at Costco, I will be looking for this each summer and buying some every year. If you are thinking about trying these water balloons I would recommend that you do!
