Rated 4 out of 5 by overall i am happy I have about 300 feet of this product in use currently. it works well and seems pretty durable. i have had it installed about a month and it has no leaks or breaking or anything like that. it comes in a roll so it is kinda tough to get it to lay strait so you will need to stake it down about every 10 feet or so.my only real complaint is the emitters do not all flow at the same rate. and it is not all because of pressure drop you will find some flowing way more than others all throughout the length of the hose. overall i am happy if i turn on the water for a couple hours it waters my whole flower bed. i have the hose covered in mulch now but i observed the flows while checking for leaks prior to burial.

Rated 5 out of 5 by Works Great! I have installed it all the way around my house, running from 2 different hose bibs with battery timers on both. Works great. Maybe the one above busted because someone didn't use the pressure regulator like it suggests... it is not a water hose after all. I plan on laying some more this fall. Helped my buddy install his and he loves it too. The fittings are easy to use, hold well, and work great.... even a "novice" can do it! September 6, 2013
Rated 5 out of 5 by Great water saver I have had this around my house for a year. It is easy for this housewife to install drip irrigation with this system! I have the individual tubes with drippers in plant areas but I am slowly replacing them with this inline one because the dog keeps breaking them. Nothing for her to knock off with this.

Rated 5 out of 5 by Very pleased with product We had just planted a small part of garden and decided to take a short trip for a week and didn't want anything to die for lack of water, so we bought and installed 150 feet of the DIG brand 1/2" drip line... this one has nozzles every 18"... they do make a product with nozzles every 12", BTW, but the price doubles. We installed a battery powered timer, which I would recommend, to save water. I bought another 200 feet and have it installed today and will add more drip line and more timers soon. I don't know how well it will hold up, but if you don't abuse it I think it will hold up. It seems to distribute water fairly evenly from the closest nozzle to the one furthermost away, but if your "runs" vary greatly in elevation, you might have to reduce the length of the run. Mine is all about the same elevation, but I wouldn't recommend exceeding the suggested 330' feet total per run (that would give you 220 nozzles). It says each nozzle flows 1 GPH, but I would estimate at 30 PSI I am getting more like 1/2 GPH per nozzle. Which is no problem... just run the water for a longer time. I was skeptical about the push in fittings made by DIG, but they work very well. I wish there was a easy way to reuse them, however. I give it a 5 star rating. April 5, 2012
Rated 4 out of 5 by Drip Hose Drip line was a easy to install and work with. It did seperate at one of the drip locations and needed to be repaired, but overall a good product. July 8, 2014
