I got this for my 4 yr old grnd dghtr. She likes it a lot. I like the remote control feature. The instructions for were basically easy to follow - (pay close attention to the wiring connections).  The stickers don't want to stay on very well, tried to wet them a little to moisten adhesive.  Works on grass as long as your yard is mowed. If you have a thick lawn, you may need something with a bit more horsepower. This struggled in our yard, but our neighbor had just cut his grass and it rode around fine. On pavement or driveway it would also be fine.  I'm satisfied with it - she it content and will get some use out of it for about a year. I do not see a 6 or 7 yr old fitting in this as it described due to lack of leg room
