Product review (2 stars): It's a low price for a reason!
The instructions are useless. Poor installation...nothing is marked for measuring, top hood is adjustable and slides into the lower hood without a way to attach them together so measuring this peace is difficult to make your dimensions on the wall. Also the screws and anchors are worthless for attaching the vent, which needs good quality screws because of it's weight. Overall, I would not have purchased this if I knew how awkward the installation would be. You have to screw the brackets with the hood attached to them, which means you have to fit your hand underneath, and the cheap metal will cut your hand! We are having to get new GOOD quality screws and anchors that won't strip the wall and we will finish this job tomorrow....If we hadn't done so much work already, I would return it. Hope it at least looks good when it's all done, then maybe it will be worth it. FYI, the man installing this is a construction engineer that can put anything together!!! so we will get it done, but definitely would have paid extra for a better product!!!!
UPDATE: installation is complete, we had to drill new holes in the hood because the pre-cut ones were way too high and you couldn't reach them. In the end, it looks good and works well. But I would still not recommend this product, installation was a nightmare.
