If you want BUBBLES, look no further.
This is the thing. Tornado is not an exaggeration.

The mechanism is a bunch of bubble wands (like those that come in a bottle of bubble stuff) arranged in a circle.
The circle spins slowly. Each wand, in turn, dips into the bubble solution, then travels around the circle over a strong breeze from the internal fan.
Voila. Like a dozen children furiously blowing bubbles!

The included (8oz.) solution produces tons of uniform bubbles.
The only problem is the solution runs out in about 15 minutes.

Buy more solution, or be prepared to make your own (millions of recipes online).
I made some myself, but it didn't perform as well (non-uniform and clumpy bubbles) as the Gazillion bubbles solution.

The design is not perfect.
The thing you "balance" the inverted bottle of fluid on is precarious at best. The slightest breeze will knock the bottle over, and there is no chance if you want to use a larger bottle.
Fortunately, I'm mechanically inclined.
Save the black plastic packaging pieces. They worked perfectly to hot melt glue into the chamber to properly support various bottles. (See pictures).

Quality control is not be the best.
One of the "wand" things stuck in the up position, which would jam the device (making it sound like the little plastic gears were disintigrating...)
I had to disassemble and clean up some "mold flash" to get it to work at all.
Sanded some rough spots.
Figured out why another wand was catching as it lifted out of the solution...

I actually spent quite a bit of time tinkering with my $15 toy to get it to work satisfactorily.

But the bubbles are just relaxation in a bottle.

Nice unit be quality control should inspect it better. When I received it, it jammed within a second of running. I could see a bubble ring got caught hitting the edge of the soap container. Only one of the maybe 8 rings hit, and only by a 1/16th of an inch. So I cut back about a 1/16th off that obstruction. That aloud the bubble rings the spin by. One other issue is the design, It stops making bubbles when the soap does not cover the full ring and it runs out of soap quickly because the soap spills out of the unit when turning. you can see in the picture, the purple catch ring at the bottom. So buy the cheap soap at the dollar store. With all that said, it does make a lot of bubbles and it's a kids toy. but I think I'll buy a professional machine and keep it out of reach of the kids in the near future.

Very happy with this product so far. It really makes a ton of bubbles. I do see a lot of the bubble mixture kinda seeping over the top and just going into the ground so for now on I will set it on a plate so salvage as much of the bubble solution as I can since I am purchasing and using the gazillion bubbles bubble solution. It really eats up the solution quickly so I want to salvage what I can as the solution isn't as cheap as most bubble solutions. I will be trying it with a regular bubble solution but other reviews I read said it didn't work as well. My Goldendoodle is spoiled and her favorite thing to do is play with bubbles but I'm typically not able to enjoy her playing with them because I'm so busy blowing bubbles as fast as I can! This has been a great solution. I definitely suggest this bubble blower!

This is by far my favorite bubble machine. Thousands of bubbles just start floating up as soon as you switch it on. The only thing is that toddlers may bump the unit and dislodge the bubbles. Otherwise you can have tons of bubbles and giggles to enjoy. I recommend ordering the refill along with the machine for hours of fun.

I first bought one of these on a whim while shopping at the grocery store. I saw it and thought my two-year-old granddaughter would love it, and I was right. She's at my house twice a week, and I'm telling you, we used this bubble machine for hours at a time, twice a week, for the entire summer. We went through THREE of the liter-sized Gazillion bubble refills (and several sets of batteries!). The amount of bubbles it cranks out is astonishing, and they float around for a long time. They float up and over my two-story house like a giant bubble cloud. In fact, we went for a walk last week, and we were FOUR HOUSES down the street and my granddaughter said "bubble!" and pointed and sure enough, a few bubbles had floated down the street! Obviously, some of the bubbles stay low and close to the ground, and she runs through them and tries to catch them. It really is that awesome.
A few days ago it died. It's important to rinse it off after use at the end of the day, and I'll be honest, I usually just squirted it off with the hose every time. I'm thinking that some of the water spray finally made its way into the battery compartment. I tried to find this same one in stores, but I had to go with a similar one by a different company. That was a mistake- it wasn't nearly as good. So I ordered this one on Amazon, and it's every bit as awesome as the original one I bought. I'll be more careful with my rinsing with this one!
