YEIBOBO !6 Channels Mini RC Submarine Toy (Black)

Great so far. Charged it up. Took 5 minutes. Might have had partial charge before we started charging. Ran it in a large bowl for a minute. Grandson filled bathtub. Ran for 15 more minutes. Was able to walk the transmitter 20 feet from the tub and it still drove and dived. Great mobility. Grandson was pulsing the dive button because he wasted it to keep moving, this might have preserved battery. Kept antenna extended full time.I am an engineer. It didn't take any special skill.Oh, sub turns on *when* it gets wet, apparently when the charging pins are shorted. There is no on switch on the sub. Instructions were silent on this point.

Great submarine!!! Durability is a good quality. Value for the money was perfect. Did happen to view the tube on this submarine prior to purchase and it was as expected.

Sub broke within a couple times of using it. Back right propeller stopped working.So we are returning this product and will look for something else

This toy works pretty well but, the range is abysmal. Once it gets about 3-4 feet from the controller, it looses signal and does nothing until it regains signal. It uses an internal horizontal propeller in the center to dive, and once you let go of the button it rises back to the surface. It is easy to use, but frustrating on how short the range is.

Right out of the box, this sub does not sink. It will float. This thing is awesome if you add a little weight! I glued a washer and two finish nails on the bottom. This creates buoyancy, which makes operating this thing a lot more fun. Another benefit is a longer battery life due to not having to force the sub to sink.

Put it in my 75 gallon fish tank and as a grown man I am having the time of my life. Greatest invention ever.

Submarine works, buuutttt.....A little too smallThe controller is flimsy and tou have to make sure you point the antenna towards submarine or it doesnt work. Also, you can only be about 6 ft away from submarine before lost signal with antenna.If you hold butting the submarine goes in circles, you will have to keep clicking buttons to go.The submarine dives but maybe like 6 inches before it floats back up. Will not stay submerged.I would not recommend unless price was less than 8 dollars.

For the money it’s a great little toy for my kid. Had fun for 10 minutes. Remote range is short but in the backyard pond that was not an issue. Battery life is a bummer (again just 10 minutes). Has a lot of character for such a small toy. Moves quite fast in the water. Lights are plus, makes a cool bluish glow when deep in the pond where you can’t see the sub itself.
