[This review was collected as part of a promotion.] This came at a time when ate actually remodeling our home. This was a very useful product and it saved us a little money by receiving it to sample.

[This review was collected as part of a promotion.] Between my home and rental properties I have 14 bathrooms and kitchens. I have successfully used this vent in drain lines that are more than 3-4 feet from main vent stack. Recently I installed it in a sink drain line that was making a gurgling sound and It totally solved the problem.

[This review was collected as part of a promotion.] I was looking for something that would help eliminate the foul smell coming from the drain. The drain previously had drained slowly and a lot of backup was created. This was easy to install and works awesome. No more foul smell and the drain now works effectively.
