Advantages: interactive, cute, makes funny noises
Disadvantages: take a long time to charge

...charge you have to stroke Gupi until he makes a happy giggling noise, then put it down and it will start to wonder about the room. As Gupi gets close to an object/wall you have to stroke its back before it crashes. This helps train it not to crash into things. It will also respond if you call it and apparently if you make loud noises or sudden movements it will run away but my Gupi hasn't done that yet. I think it may be concussed from all the walls ...
...If you put Gupi in the dark it gets scared until you comfort it then he will wonder around quite happily again making its funny little noises. Then you push a button on its head to make it go to sleep and it snores! When it needs charging Gupi stops and shakes its head while making yet more odd noises. Gupi comes with a small plastic carrot which you can use to guide him around with. You can also put it in his mouth when you are trying to comfort ... Read review

Advantages: Massive amount of differnet controls/settings/functions
Disadvantages: Will start to get SLIGHTLY boring after a couple of weeks.

At the time this was released, it had to be THE best piece of technology around, and still manges to hold its own weight now, despite the advancements, namely the V2 and the media edition of the robosapien. With a massive array of settings and controls, ranging from dancing, kung fu chops, walking, burping/farting and everything in between, this has to be one of the more fun toys i have played on.

...robot to act them out on your behalf. Using a special detector within the robot, 'Robosapien' will automatically walk AWAY from objects such as chairs. The one problem with this is once you have gone through every command a couple of times, you will resort to bringing it out a couple of hours a week, rather than per day. ... Read review

Advantages: Great settings and functions for the price
Disadvantages: May be dissapointed if you have used Robosapien before

...kit considering the price. The roboraptor has the ability to roam, growl, move forward backwards, left and right, all controlled by a Playstation-esqe type of controller. When knocked on, the raptor growls, and moves its head. Every body movement made by the raptor is fuid, but the walking is slightly more robotic. By pressing sensor pads on the raptors back, you can make him run away. A nifty piece of technology, but do not expect the vast amount ... Read review

Advantages: Sorry, None, Even the price is too much, compared to more serious models.
Disadvantages: Uncontrollable, Bad transmitter/receiver set, Too expensive, no replacement parts when damaged.

I got one as a present, two months ago, not hindered by any knowledge about rc helicopter flying. It took me about 2 hours to crash it in such a way that the helicopter was unrecoverable. ( broken tailboom ) The transmitter / receiver set is crap and caused me to loose control in the last crash. The helicopter was about 30 yards away from me and could not be controlled anymore. Having read a lot more about rc helicopters and buying a more serious ...
...the Nikko: -- The fact that it has only 3 channels for control makes it impossible to control. You need at least 4 channels to succesfully hover a helicopter: 1 Throttle ( up/down ) 2 Rotate tail 3 Forward / Backward ( elevators ) 4 Roll left / ri
