Product review (5 stars): Great tool, easy to use.
within 30 minutes of receiving, I had used this kit to clean our dryer duct vent. It did a great job as it was able to navigate through two 90 degree turns and continue on down the line with just a little effort. I did gorilla tape each connection as I added them, but it may not have been necessary. You must remember when you retract the length of cleaning wands not to reverse you drill. Keep it in forward at all times and pull it back out of the duct while doing so.  Jim
