    Missing tab on vent control
  

*by M***N on Reviewed in the United States on January 5, 2015*

I like the quality of this diffuser and it's appearance, however it doesn't have the white tab on the vent control as pictured. There is just a metal piece that sticks out from the unit to control the air flow. I feel it is dangerous because  children could fall against the diffuser or accidentally step against it and get cut. I ordered a second diffuser to replace the first one since I thought the knob for the unit fell off before shipment (since there was no knob (tab) in the box it came in) but the second diffuser came the same. It arrived with no tab on the metal. I called the company directly (Hart & Cooley) that makes this diffuser, and they informed me that this newly designed  diffuser does not come with the plastic tab on the vent control. I think that is crazy! We installed the unit as it was, but my husband made a small wooden knob to put on end of the metal protrusion used to control the air flow so no one gets hurt on it.

    Perfect fit. The big box store version was not ...
  

*by E***K on Reviewed in the United States on April 2, 2018*

Perfect fit.  The big box store version was not deep enough and left a 1/4 inch gap in front of the register.  This one covered the entire opening perfectly.  The lever on the front is a little sharp but didn't matter as we do not open or close this vent. The pictures are a little confusing as to what the louver pattern is.  The item received had a different louver pattern then the picture of the the item on Amazon at the time I ordered it.  However it appears the picture may have been updated since.  Only register like this in the house so we didn't care what it looked like but maybe disappointing to someone trying to match existing registers.

### ⭐⭐⭐ 







  
  
    Not the match I was looking for.
  

*by W***Y on Reviewed in the United States on April 14, 2014*

I was trying to match other diffusers in my house, one of which I recall finding an exact match with  Ameriflow several years ago. . American Metal and Ameriflow are supposed to be the same product, same company; the American Metal product pictured appeared to be a match, but the center triangular opening is partially covered by a label in at least one of the photos and this masks the pattern, and it was not a match to the rest of my house, so I had to return them. I was very happy with the return process and the diffusers themselves appeared much better quality than the also similar Truaire ones at the local Home Depot. Unfortunately, I am still searching.
