AC Drain Line Cleaner Tool

While its a nice concept, it dosent work. It might work if your drain line is a foot long, but if its longer than this, this tool is not powerful enough. My drain line is 10 feet long and this did not have enough power to clear it so it was worthless to me. This should have been mentioned in the description, if it was i would jot have boight it. A waste of $85.
