I purchased this product thinking it was built a little more substantial than what it is. It is all
some type of plastic material.

I love the design, but the motor is substandard.  It cannot handle running more than a few hours at a time.  I have to add water into the bowl and into the top hole to get it started.  I only run it on the weekends.  However, the last weekend I had it on for over 5 hours and the motor just stopped.  Not sure if it will turn on again.  I've only turned it on 4 or 5 times.  I think we will need to replace the motor.
