The tealight candles that came with the fountain are NOT the average tealight candle. They were very thin and burned out in an hour. They are also smaller in circumference than 'average' tealights; therefore, my 'average' tealight DO NOT fit in the candle holders and the tinfoil portion of the candles is visible and ugly. 
But, the fountain works great and the pump is very quiet!!! The sounds are soothing in my little apartment.

Pros: lightweight, small, quiet
Cons: tealight candles don't fit in space...normal tealight circumference is too wide.
