I have the XOP pyramid shaped hood over my 30 inch Wolf rangetop. It's 600 cfm and that's plenty for us. I rarely use all 4 burners at once. I can see the steam and smoke getting sucked up even on low setting (it has 3 settings). The light is also quite bright, which I like.

I got the XO over the Zephyr of the same style because of the extra CFM, tough it was a bit more expensive.

I would appreciate a lower speed. Kobe has something they call "QuietMode" that is a special low-noise low speed in a similar hood that would be another option, although I think Zephyr does a better job of making the grease cups less obtrusive - they're built in, don't hang down like they do on the Kobe. As I say, though, that's a minor issue - of course, silent would be good but for me the functionality is the main thing and that's excellent.

I bought an XO range hood and have had constant problems with both lights. The lights have a mind of their own as they will turn on and off in an instant. I have replaced both lights and the problem persists. Can anyone offer a solution? Very disappointed in this product and would not recommend to anyone

How old is it? XO has a 2 year warranty. If its pretty new, I would call the main distributor. Thats a company called Eastern Marketing.

Joe, have you installed a number of these hoods and do you have a sense of reliability? Thaks in advance.
