Really cool little RC car, my 6 year old loves it! Got it for his birthday and took it to the beach hotel, works well on grass (lots of grip to flip), works well pool side (less grip but can get it to flip), works in the water driving in and out and eventually pulled up the courage to fully paddle it in and out of the water, and works well on the beach sand, wet sand, but gets a bit mucky, but as it’s waterproof, easy fix!! The only gripe I have with it is the battery door isn’t the easiest to connect and could be a bit better to easily fit and seal. Just needs some metal sleeves where the screws fix instead of the plastic currently there. Great gift for a 6 year old!!!
