Review on SYMA Q7 RC Boat: 20+ Km/H 2.4GHz Fast Racing For Pools & Lakes, Capsize Recovery + Low Battery Alarm, Gifts For Boys & Girls by Drew Springer

We have enjoyed these boats in our pool. We live on a salt water canal, so we can't run them there. We actually took them to a friends house because their pool is much larger than ours. They are so fast it was hard to control them in ours. But with enough room they are great! Each one came with two batteries, so you just keep one charging at all times so when the battery dies (it starts to beep) you just swap out the battery and away you go. Great boats for the money.
