This thing is a great first boat. Came with two batteries as described. Servo and throttle trim was switched on the controller though for some reason (trimming throttle actually trimmed the steering and vice versa). Boat takes on a little bit of water after running for 10 minutes. Not a concerning amount though. Just tip it out and let it dry while waiting for the next battery to charge :)
Very fast boat and easy to use. I don't put the maximum rating because I find that a little too much water enters the boat and there is a bad distribution of the components, the boat leans to the left side.
