For nearly 20 euros corresponding to the expectations. Unwrapped, batteries (buy extra! 4xAA / R6 / AA) into the pure remote control device, and boot connected. Full power there only when the battery has been a couple of times charged / discharged. Starting in grandpa's pool and immediately everything chic. Relatively quickly (once had a similar thing was much slower), good cornering (turning only one screw), good straight ahead. Just a little wave, then it dives already, so it is not seaworthy.
Two electrodes ensure that the motors run only in the water, so that no components may be damaged by significantly higher speeds in the dry. It also runs quite long and can only very gradually. Then charging time about 3 minutes.
Lief already several times, fun, perfect for pool. Great fun for my son (and me ;-).
