These are exactly what you expect - plastic vent flow deflectors that attach with magnets. The first one I used on a smaller vent (13 in wide). Fits securely and pretty flush. The other vent is about 17 inches wide and as you widen the deflector across the span of the vent, it ceases to stay completely flush with the vent as the plastic tracks become separated from the grooves through which they slide, thus causing a droop in the middle part of the deflector. Still functional, just not as flush to the vent as I'd like as with the smaller vent. All in all though I'm happy with the product and would buy more at this price.
