I just got mine in the mail and here's my review so far (*haven't installed it yet):

1. Its big - lot bigger than you would think, even knowing the measurements. I haven't had time to fit it up yet but hope to this weekend.
2. When I got it and opened the box, the filter and shield were assembled and put in a sealed bag - removing the bag the shield was all smudged up and taking off the shield was tough - turns out the lip where it inserts had a small bend in it. Removing the filter, I noticed that 3 fins on the venture were broken off - wtf!??!! I then noticed that there were some breaks in the filter and was convinced that I got a return or something. Then I looked closer and realized the tears were from the rivets they used on the inside - why they didn't use smooth rivets I'll never know.
3. The filter may be good, but the overall quality I thought was lacking - the fact that the "venture" had broken fins, the bent lip, banged up and smudged cover and light tears on the filter material all scream "rush job" or "crappy chinese import" - I haven't emailed Tone yet and am sure he wasn't aware of anything being amiss - wanted to take some photos first. I'll post them here when I do.
4. I haven't corresponded with anyone else who bought it so I'm not sure if the issues described in #3 above were specific to the one I got or is indicative to the product - we'll see what happens when I contact them (or Tone).
5. You may want to wait until I get things resolved until you commit to buying one - they're rather expensive and at this point I'm rather crestfallen - everything hinges on the customer service aspect now. I'm emailing Tone with this post.
