The product works fine. It comes with a plastic screwdriver to remove the plastic screws. This is rated for use by three years of age and up. Our grandson wanted to "fix the firetruck" because of the screwdriver. The screws are very easy to remove. What do little children like to do? They put things in their mouths, like little, plastic screws. Very dangerous. How about a bubble gun that is just a bubble gun? There are plenty of toys to encourage fix-it play that are not inherently dangerous. This will go back. If you do purchase, I would put a dab of superglue on the threads and get rid of the ridiculous screwdriver.This bubble gun pretty much met my expectations. It is sturdily built and does not leak.Some things to note:- The on/off switch is the trigger. You don't have to hold down the trigger for bubbles to come out. You just have to click it once to turn on and click it again to turn off.- This thing takes 3 batteries to run. The diagram that shows the polarity of the batteries is actually reversed. Not sure how they got that one wrong, but you should be fine if you just align it by putting the "-" end on the terminal side with the springy thing.- Plays music- Comes with a screwdriver tool toy that lets you adjust and take off different parts of the fire engine. I thought this was a totally unnecessary addition, but my kids seemed to really enjoy it. So, what do I know?- Bubble come out a decent size (like 1-2 inches in diameter)The plastic is pretty durable, bubble solution and batteries lasts long enough for the kids to have fun a long time. Works like it should and easy to setup for the kids.My toddler is crazy about fire engines and this definitely made his day. It is very realistic looking and also comes with a sound feature. Colors are very vibrant and it came assembled. It also has a screwdriver which can be used to disassemble this toy. Only minor drawback is the music is good but no fire engine sounds.Kids love bubbles! It is so cute that it is shaped like a fire truck. We try to stay away from things that are shaped like guns so this was adorable. This was a fun machine for them. It is cute. It worked fine. It is great for the home or parties. They really loved it. Everything worked just fine. I would recommend it.My nephew loves this Bubble Gun. He loves Fire Trucks and bubbles so this is perfect for when he comes to my house and I babysit him. My dog also loves it. Such a cute design they created for kids to have fun. Great price also.Cute hands on way to blowing bubbles without worrying about spills. Requires 3 AA batteries
