eMart Mini RC Electric Toy Remote Control Boat Submarine Ship Waterproof Diving in Water Gift for Kids - (Yellow)

Great, works fantastic, now I'm knowing what to do, Great fun.

It was going so well then a week after the return window closed it developed a fault where it dives every time I turne left.

Used in an outdoor swimming pool down to 1.4m depth. Works really well and a lot of fun for the kids (and adults).

The media could not be loaded.  Great little RC submarine, only for indoor use in clean water.I made mistake on the begin and tryed to use it in the after bath water.The hair made both propellers stop working. It toked me few minutes to free the them.

Fun little toy but the rudder impeller gets stuck. To fix carefully carefully pry off the rear cover panel over the impeller and reglue in place about 1mm further back.

Great little gadget. Used most evenings at bath time for my son.

Drives stable and quite precisely with a bit of practice! the impeller is so small as well it's great to drive without the risk of hurting anything in my fish tank, i use it quite often to deliver food to my fish which makes for some good fun! only small gripe is the buoyancy of it fluctuates over time, it will sometimes only manage a slow ascent and other times it will surface very quickly. either way cheap and functions well!

Sounds like the sub. does what it's supposed to and dives under the surface, but not very deep, so reports say.
