I am giving 5 star only because of my son. Pros - 1. Very power yet flexible. Can be used on tough terrain. 2. It has flexible rubber tyres as well as good shock absorber. 3. Good look. The best among all the remote control toys I have got it for my son. Cons - 1. To recharge the batteries, it is required to remove the batteries from the toy for which a star screwdriver is a must. It is a very painful exercise. 2. The wire connecting rechargeable batteries break very frequently. A soldering iron is required every time the wire breaks. (Refer picture).
