These LED candles are identical to those sold in lots of 20 by the same vendor as B00J3K6J7Q reference.
They are fully consistent with the description and are perfectly watertight. They resist even in the freezer since I've used to make mini-icebergs.
Important: these candles do not float! It is well marked "submersible" in the description, for once it's not a rough translation ;-)
I have not had any problems with the remote control that works well to do in time.
The batteries are of a standard model and can easily be replaced: attention to the price of the batteries, however.
