This is a pretty decent rock crawler and at its price point this is exceptionally good.
Pros:
1. Quick charge time and run time of 25-30 mins. Li-ion battery provided.
2. This crawler is a bad ass and it has the adequate power to climb cemented staircase, bricks, mud, gravel and even a damn shallow river. Provided you plasty dip the electronics in the crawler.
3. The range is decent and you can cover a good distant in the open. The double AA battery on the remote is a huge saving when compare...
