Product review (3 stars): Mixed feelings on this review. poor support and poor packaging.
Ok.  Not a bad value for the money but not great considering the aggravation.  Mine arrived dented and creased on both of the hood slides. I blame this on poor packing by the manufacturer. Fyi. There was no sign of damage to the shipping box.  I read many similar complaints on this issue as well. The instructions are lacking yet it's not that complicated to figure out.  It took 10 days for me to receive the parts to fix it and they don't answer their emails. It would have been only one star but I like the style and it blows a lot of air on high. On the good side I only needed to send them pictures of it damaged and serial numbers and they send the parts FOC of course.
Tips.
1. Dry fit with the frame only (no stainless hood sliders) so you can get the height right. Brackets will need to be cut with a sawzall or hacksaw.
2. Before you reinstall install lower slide and screw it to bottom of the hood under the vent screen.  The directions don't mention this step. Be careful not to chip the glass because it will chip much easier than you would expect. I did but it's small an unnoticeable in the top corner of the glass.
3. Use some tape and cover the edges over the second inner slide before mounting the hood. It's sharp and it may scratch the inner slide and or you.
Good luck if you are cheap like me and buy this anyways.
