Product review (1 stars): Seriously: Don't Waste your money
So, we wanted a good looking chimney style vent hood that did not break the bank to replace our over the range micro which was completely useless for removing cooking smoke and grease. 640 CFMs for less than $300? Decent reviews on Amazon?  Sold! Are the rest of you reviewers paid by ZLine? Because this is the biggest piece of garbage, waste of money that I have ever invested in. Saying a lot, I know, but read on...

For the price, I did not expect this to be on par with a Ventahood, or even a lower end Broan, but I *did* expect it to function, at least minimally. Word to the wise: you get what you pay for with this one. Had it not been too late to return this item without a hefty $100 shipping fee by the time our kitchen remodel was almost complete and we were ready to install, this would have gone right back. Unfortunately, we found that there is zero useful information on the company website, much less a human to talk to. Just try to find any information on the ZLine website, and you will see that this is a shoddy company---no useful contact info, product info, etc. Cruddy piece of garbage made in China, although the company as listed in Ohio. . The back story, for those who are interested in details:

The product arrived missing a critical piece (back piece for holding the chimney sleeve), but the vendor replaced right away. So far, so good. Then the problems began...

First, one of the halogen bulbs was DOA. After reviewing the cr@ppy installation manual, which listed the page for replacement incorrectly as page 23, but alas, is actually on page 25  (seriously? They can't bother to proofread the instructions?), I set about replacing the bulb. Had I actually attempted to follow the instructions provided (again, on the wrong page) , complete with inaccurate and completely indecipherable instructions and diagram, I would have broken the not only the entire bulb, but its housing assembly. Luckily, I'm fairly handy and not a complete moron (well, except for purchasing this thing:). The holes for the light bulb were honed incorrectly, uneven and nearly impossible to get a bulb in, but after working gently on it for a while, I eventually got it to work. Still, this process took much longer than it should have, and frankly, I should not have been forced to deal with it right out of the gate.

Fast forward to installation a few weeks later: terrible diagrams and instructions, yet again. Our contractor got the main body up with just a few annoying issues. Then, however, the problems started again. Included with the vent hood is a plastic flexible duct piece. Umm, not only is this type of flexible plastic duct not to code just about anywhere in the US, but it is a fire hazard. The manufacturer knows this, of course, as they state to use rigid ducting. So, why include an unsafe and against code component at all? Lack of integrity, I would gather. Off to the big box store to get yet another part for this new piece-o-junk, this time rigid ducting in the correct diameter, and then...

The bar that holds the chimney cover was bent, and would not allow the sleeves to slide in correctly. After an hour of cursing and finagling, contractor and DH evidence to snip the sides of the sleeve to allow fitting. Eventually, it works, sort of. Whatever, we are over it t this point. We figure, pice of junk but now it's done! Turn it on! And!  Ummmm...

At full speed, a defeating roar I might add, this thing does not even cause a piece of paper to flutter directly underneath its vents. Completely and utterly useless. 600 cfm? My @ss.
