Query: Didn't work for us

I bought this mower for my daughter who is two. I took advice from reviews here when it didn't work, and followed the included instructions (and troubleshooting) carefully. We tried cleaning it, we used different bubble solution, and the only way we could get it to make bubbles is if I pushed down on the mower and ran with it. It took a lot of effort for me (and my husband) to get it work, and there was no way our two-year old could do it. We returned it. Great concept for a toy, just too much trouble.
