Difficult to follow instructions since item came with 2 different sets of instructions and two different water pumps.  Finally assembled with the replacement pump sent with the fountain and it works.  Unable to use the "rechargeable" battery sent.  Once working it is very nice.    Looks great at night with the lights and the fountain working.  Do need sunlight for pump to work but there is a long cord so you can place the fountain in one area and the solar panel a fair distance away for sunlight.
