My experience may just be that I got a item with a defect from the factory.. The fountain is very nice I bought it to put in a terrarium for a chamelion..the small water pump keeps falling off of the hose to the top of the fountain and when i plug it in i have to jiggle the plug around in the outlet and tap on it to get it to come on I have tried several different outlets. also the plug on it gets very hot after a short period of time. I do love the fountain just wish it worked 100% then i could be satisfied 100%
