Query: Some Are Just Lemons

I have used this fountain over the years, and buy a new one when it needs cleaning. Bought one in May 2012, worked great. Needed cleaning in October, so I bought this one. It leaked around the motor, badly. And yes, I tried to remove and reinstall the motor several times in an effort to stop the leak. No luck. So I threw it away and ordered another new one, which also leaked in the same spot. On that one, I tried to stop the leak with acquarium sealant, no luck. When this little fountain works, it's great. But there are certainly lemons out there!
