I purchased the Terrain Twister for my grandson's 7th birthday and he declared this "the best toy ever!" I was impressed with the toy's agility, it had no difficulty traveling across long wet grass, wet leafs, snow banks and the most fun environment, a small stream. It certainly lives up to its description. Just turning 7, he had no difficulty manipulating the remote control. He had the greatest time with the Terrain Twister in the stream, going back and forth, and climbing up the icy edge. He named his new toy, " the Ice Green Machine" and the Best Toy Ever, he said it was better than an RC car because you can't take it in the water and better than an RC boat because you can't take the boat on land. The only draw back is the battery life. The fully charged battery lasts about 20-25 minutes and he wasn't nearly ready to stop playing so we plan on purchasing another battery for a ready backup. He gives the Terrain Twister two thumbs up! And one very happy Grandmother!
