The first bubble mower I received did not work, it wouldn't blow any bubbles. I looked at all the reviews and did what everyone suggested: cleaned it out, started again, diluted the bubbles, tried some different bubbles, but it just didn't work...the blue wheel had bubble solution in the holes but it seemed that there was just no air coming out of the outlet to push any bubbles out...so I sent it back. The new one arrived this morning from the online store I bought it from, no quibbles, and once I'd pressed down the bubble container for the 15 seconds and started pushing it, immediately a massive stream of bubbles came pouring out! My little girl laughed so much and followed me round the garden shouting 'more!'...very pleased with it now!!
You can't go wrong with a classic bubble mower! The clicking sound it makes can get a little annoying but it's supposed to mimic a mower and make a sound so I guess that's okay. Bubbles come out great.
