It is indeed very fast, it turns itself upside down and it is not only for waves if you drive it slowly because literally it went inside the water every time I ran it with waves several times and inside where the battery is, it had several drops of water. The battery is so-so, lasts about 10 minutes but what do you expect, it's not like you're living there. Also, its range is not great, it reaches and doesn't reach 30 meters
