### ⭐⭐⭐⭐⭐ Review
*by A***R on 7 April 2017*

This item worked perfect for me. It's much better than a solid duct. I used a 4" hole saw and the flexible duct will go through with no problems. When i tried to fit a solid duct through the same hole...not a chance. I purchased this for a bathroom fan and i;m very happy with it. Easy to pull and to make any necessary turn. The price was competitive as I tried multiple other web sites.
