SHARPER IMAGE RC Gravity Rover X-2, Zero Gravity Wall & Ceiling Climber, 2 Rechargeable Batteries + 4 Extra Propellers, Wireless 2.4 GHz Remote, Stunt Space Rover Car, LED Lights, Easy Kids Indoor Toy

Its such a neat idea. It's hard to criticize when a device is exactly as advertised on the box, but its such a mediocre product. As a remote control car it is pretty bad. Straight isn't quite straight, but constantly turning slightly left. It is slow but it not for speed. Turning on the "gravity" effect is jarring due to how loud it is. Seriously, it's hard to have a conversation in the room with it on, but it does it's job, moving the toy along the walls and ceiling (if it can traverse your crown moulding). Its small so anything on the walls or ceiling it likely won't get over. The fans on this thing are rediculous and move a lot of air. It has issues navigating on some (smooth) wall surfaces. But the remote, the controller is so bad it makes the rest of this seem pretty nice. It really just forward and backward for each the left and right side. No idea why but they chose to use smooth low profile sliders instead of sticks, and they are hard to push even for me. Even when you are pushing them the car barely registers it, or takes several seconds before actually registering the command. Combined with the car not actual being capable of going straight, it makes navigating around anything a chore. Anything short of driving in a wide sweeping arc is outright painful. I can literally keep going about the issues with the design and execution of this product, but I'm done with it. Feel free to get it for your kids for christmas, They'll be excited when they read the box. When they try to use it the excitement quickly wears off, and it can return to it's box in a corner of their room, that's where mine sits.
