GoolRC Remote Control Submarine (White)

First, I need to say READ THE INSTRUCTIONS! Particularly about swishing the tail end around in the water before using them. The subs use tiny little thrusters in housings that are small enough to trap air in rendering them useless, hense the swishing part to get the air out. Despite the tiny size of the thrusters, they're surprisingly responsive. Just remember that these are subs, not speed boats. I was surprised that these use actual, proportional ballast to control their bouyency (surfacing and diving mechanic) instead of a thruster like most others, this allows you to surface or dive in place and also trim the sub to stay at a desired depth. All in all these are amazingly fun especially for the price. They're small enough for tub fun but maneuverable enough for pools and small ponds as long as the water is clear. They also use an auto surface feature if they don't get any input or lose signal for more than 10 seconds which is a life saver. Highly recommend!

Very small

This works, but it’s a bear to “drive.” Despite experience with rc gear from high end trucks to airplanes and drones, this thing is hard to manipulate. It’s overly sensitive and finding bouyancy is a nightmare. Steering is slow and cumbersome. While it does basically do what it’s supposed to do, it was a five minute novelty for everyone in my family, from 12-47 years. It’s not worth the money whatsoever, in our collective option.

Great fun for 6 year old grandson. Had to buy one for myself! You can hear the ballast blow before submerging. For a large amount of water like a swimming pool, stick the tip of the antenna in the water to carry the signal. Very maneuverable.

works like a charm the only thing is charging is a bit difficult if the submarine doesn't work just make sure it's charged and the batteries are working.

Great toy for kids. Works under water, easy to charge, great bath toy and for the cost it's awesome 👌

Just got ours today for my son, we opened the package and charged it up while reading the manual. Once we tried submarine it’s not working.

Very cool toy and can be educational. Smaller than expected but works better than expected. My daughter loves it so automatic 5 stars. The control placement could be better but it doesn't ruin the fun. I'm pretty sure it could be sold cheaper without sacrificing quality but guess you can always for it to go on sale.
