It was ok. Bubble solution clogged up around the holes so you have yo keep wiping itGot this as a gift and the kids loved it. It has a single 18650 cell that comes with a usb cable for charging. If you’re not careful with the charging the battery could overheat so be carefulI got this for my 3 year old for his birthday and we all love it! The bubble output is insane and it's so easy to use! It comes with a charger and the only inconvenience is unscrewing the cover (one small screw) to charge the battery but is well worth the fun my son has with this. I'm considering purchasing a few more to use for wedding pictures, the output of bubbles is amazing.So much fun!Got for our son for his 7th birthday. He loves it. it works well and comes with plenty of bubble solution you can make.At my big age I play with this more than my son.This product I bought for my nephew and he is very into bubbles and when I charged it up this machine really over came my odds it was just amazing, the only thing I had wrong was all the bubbles somehow leaked and popped all over the place but I had a jar of bubbles I bought earlier which it worked fine with also, other then that this product is just amazing!!!For my granddaughter to play with she love it
