I bought 2 of these jeeps, the military and the turbo ranger. They purposely don't put how fast they go because they only go about 1 mph. I thought they were a good price because I have a 2 and 4 year old but they are really slow. It's fine for the 2 year old, but too slow for my 4 year old. They dont ride on grass, only hard surfaces. I think they aren't worth the money at all.
