I just bought two of these at Target for $9.99 each! They come in 27mHz and 49mHz, so I bought one of each. Unfortunately, the 49mHz model didn't work out of the box, so I'll probably exchange it tomorrow. These cars are distrubuted in the U.S. by MGA Entertainment. Here's the page on their site dealing with the "Micro Blast Racers":

(scroll down to the bottom of the page.)
This is my first Micro RC car, so I don't have a lot to compare it to. From what I've read here and at other sites dealing with micro RC cars, the MBRs have a few unique features.
1.) The fact that the steering is controlled by a motor is interesting, but it isn't proportional, so I'm not really sure it's any better than the magnet type. Perhaps the fact that it has a more gradual 'attack' makes the steering a little smoother.
2.) The controller is great. It has actual joystick-type levers to control forward/reverse and steering. It's almost like a slightly miniturized Playstation controller. Again, since I don't have experience with other micro RC's, I'm not sure how it compares. It definitely
seems like it would be more ergonomic than, say, the Microsizer or Zip-Zaps controllers.
3.) The charger is separate from the controller. The disadvantage is that you need more batteries. The charger takes 2 AAAs, while the controller uses 2 AAs. On the other hand, I would assume that the batteries in the controller will last longer, since they won't be used to charge the car. At any rate, I picked up some NiMH rechargeables for both, so I'm not too worried about it. The car charges in about 50 seconds, which results in a 2 or 3 minute run. I've found that running the charge cycle multiple times greatly increases the car's run time.
The parts don't appear to be interchangeable without some fairly extensive work. It's certainly not engineered for easy customization like Microsizers. The performance seems pretty good, however, and I'm really having a blast driving this thing!
Anyway, I hope this information is useful. I've found next to nothing about these cars anywhere on the Internet, so I felt it was my duty to add my $.02!
