The kids have had it here for six months and they're thrilled. It is quite durable, has 2 speeds, slow and fast, 3 settings for the lights—on, off, and motion-activated mode. It goes on almost any terrain, has front lights, turn signals, brakes, the 500mAh battery lasts about 25 minutes, charges in 1:30 hours, and finally, it has many extras you can find (I bought the metal protective bumpers, which also add a bit of weight so it doesn't jump abruptly at high speed and is more stable, and a second 1200mAh battery for 60 minutes of play and charging in 2.5 hours). It is available from 2-3 companies (MN99S, AmewiD90, and one more, but the model remains the D90).
