Query: expensive junk

My Walmart generic pet fountain burned out after a year, so I thought I'd upgrade to this more expensive model bought at Petco. More expensive must be better, right? After reading that the fountain, including the motor, is supposed to be disassembled and cleaned weekly I was hesitant. And the plastic fountain didn't seem any different or better built than the cheaper fountain. After the first cleaning, the Drinkwell leaked and was un-usable. I'll just buy a cheaper but more reliable version from Walmart, and the Drinkwell will go in the garbage.
