I just got my three boats, and they suck! They should be called "Slow Speed" Boats, not Speed Boats!
They take about 3 minutes to charge, and the hull gets very warm. You have to switch the boat off to charge, and don't forget to switch it back on again when the charging light goes out.
Put them in water, and it is impossible to get them to go straight because one motor always runs faster than the other. At best you have to zig-zag to go straight.
I have one boat that only one of the motors works reliably. Press the button three times, nothing. Press it a couple more times and the motor might work. What a PITA.
And to top it all off, all three work on the same frequency! It is impossible to have a race between two boats. Although I was LOL when I put all three boats in the tub at the same time and controlled them all at once with one remote control! It was like a boat demolition derby.
The thing that had me ROTFL was the instructions that say "Remember to avoid water."!!!

and "Don't play outdoors during thunderstorms" and "Wipe clean with something like a a towel after playing"
and"The toys is designed for indoor use only. Outdoor use may lead to malfunction caused by dirt or waste"
and "Bring back to shore before the battery power is running out". (I thought this was an indoor toy only?).
I think they need some help with their "Engrish"!!!
They are kind of fun, and I've certainly blown $25 on worse stuff, but make sure the motors work before you give them to a child as a present, or you may disappoint a kid on X-Mas...
