Who ever designed this model should be fired. First of all, the info on the product page is not consistent. Is the CFM 900 or 500? The prod description has it at 900 while the Specification section reads 500. We bought it bec we thought the CFM is 900.
 Now back to the design issue, the lights are at the back of the unit. Seriously? The grease would accumulate at the back and drips out of the lights.  The baffle channel's edges are so sharp that you can use it as a steak knife. It does come with a grease cup but there are no tabs on the motor for you to clip the grease cup on so it's useless. Then the baffles are so flimsy. They came out of the package with screws missing. 700  bucks gives a poorly designed, carelessly assembled product. Big disappointment.
