Product review (4 stars): Good Value, but Not Perfect
This vent hood does the job.  I'd give 5 stars but for two things:  First, I had trouble getting it to fit over an old galvanized vent pipe...that's probably normal, but the seam split.  Second, the screen snaps in place and it's hard to do that if it's low to the ground.  A sliding screen, like other's I've used is much easier to clean.
