Product review (4 stars): the series of dryer that I own appears to but super rough cut as all the edges are sharp
It does what it is supposed to do.  Unfortunately, the series of dryer that I own appears to but super rough cut as all the edges are sharp.  I had no issue with fitting this thing together, and getting it in place.  I had no issues with measurements of any sort.  (I vented to the right if you're staring at it from the front)

All I can say is, be careful when sticking your hand around any of the metal edges.  My dryer got it's blood sacrifice.
