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.

Just opened the box, it has no charging cable and I have to purchase one to charge. And the. Charged 3 hours it doesn’t work !!!!

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.

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

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.

My submarine did not come with the little screw drivers nor did it come with the actual manual to be able to understand it. Honestly buy from a different brand not sure if this happens to everyone but it sucked.

Instructions could have bee clearer on initial opening, required Philips screwdriver that was supposed to be included not there.And yet I gave it five stars.After figuring out what was required for initial operating and providing my own screwdriver we got an amazing amount of fun operating it in the bathtub. My 8 year old grandson-unit played with it a lot. Unlike helicopters which use a lot of battery for lift, the sub floats so the batteries last a long time between charges. It is also safer, unlike helicopters or drones that can go anywhere and damage furnishings, the sub is confined to water and it is hard to break a bathtub.
