GoolRC Mini RC Submarine for Kids, LSRC-SMI Remote Control Boat Waterproof Diving Toy for Boys and Girls (Blue)

This thing is quite fun kids love it

Its kinda hard to get to work. Really specific instructions and a kid would probably never read the directions.Couldn't get it to work in the bathtub. And, its definitely NOT MEANT FOR A POOL. They don't specify that all to boldly on here.

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!

I gifted this to my friend for her to use in her 40 gallon fish tank! She loved it and put it to use right away, terrorizing her fish with it!! I don’t recommend terrorizing your fish but it’s good to remind your fish of their surroundings

Water built up in the remote after 2x using now the sub goes bonkers

I use it to annoy my Gar. Worked great before it was bit on the propeller section. Just dont try using it anywhere with a current.

It worked for about 3 minutes after the initial charge. Now it won’t charge at all.

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