I like the product. You must use the 25 PSI converter to make the drippers perform as expected and you must be very careful when inserting the dripper in the tubing. Only twist the tubing around the nipples. Do not bend the nipples or they will break. Once installed, they do a good job of watering.

Some of my drippers in my 1/4" inline drip tubing became clogged. These drippers were great for cutting out my clogged dripper and replacing with the add-a-dripper
