These are great "fast" little RC boats! Unless you have a big pool, you might want to stick to fresh water ponds/lakes to really open up the throttle. My son and I still had some dual (yellow/green) boat races in our swim spa, since they have nice tight turning radius when remote is toggled to 7:3, rather than the 5:5 rudder ratio. Battery life is good for motor power consumption and charges well with USB. Boat hatch seals nicely to keep water out of the elec hull. Nice that each boat comes with 2 batts for more race time! I would definitely recommend purchase to anyone who wants a little RC boat adrenaline rush.
