I know this is currently the #1 best seller in bubble solution. However, gazillion bubbles is a far superior product. Gazillion is little more expensive, but after many years of entertaining little ones, it's worth the few extra dollars. Believe me, I love saving a buck where ever I can - so I tried this. On the positive side, Miracle bubbles does a good job for the casual user. I have found this is an excellent refill for those bubble guns they sell at resorts, fairs etc.
