Got this so that the grands would have something fun to play with here over the holidays (instead of "having" to build some of my construction set collection or game...) and I believe it to be a good choice and should be a hit.It comes with an extra battery so that you can charge one on a USB port while running the other, the only batteries you need to provide are the 2 AAA's and I used rechargeables that worked fine.The car is FAST! It's a hoot to drive, as it'll spin, go sideways, snake, hump-up (which shortens it slightly), and even has an automatic programed "dance" mode, that is a stitch to watch. We put it through it's paces, with and without music and lights (which I'm sure they will like, but we're not so thrilled with for us) and it worked flawlessly. It's a bit of a challenge to control around the house, I'm sure that when the kids are here we'll see how it goes outdoors.It seems very solidly built, as it has some heft but runs amazingly fast with it's small rechargeable battery pack. We didn't test the wrist controller, we figured that he kids would try it out, as we had a hard enough time learning to control it with the regular controller. I really like the fact that you have so many options with it, and it seems to be very responsive to the controller. It took no time at all to have it up and running out of the package.I believe this is a great deal for the price, as it does so much more and feels much more solid than other RC units that we've had in the past. I'm hoping it lasts, but I'm sure it's going to be a big hit!...
