Review on SYMA Q9 RC Boat For Kids - 10Km/H Speedboat, Double Power & Low Battery Reminder by Eric Grayson

RC works well, however, battery life is very short, less than 10 minutes, exchanging batteries (comes with 2) is tedious and requires removal of a small screw which WILL ultimately get lost. I recommend that this product NOT be used in a pool as that shortens battery life further. If the boat stops in mid pool, and fills with water, it must totally dry out to be used again. Because of the short battery time, my 8 year old grandson lost interest pretty quickly.
