Rated 4.0 out of 5.0 by Great Way To Water in the 21st Century I am converting the flower beds from spray heads to total drip hosing and adding a permanent drip line (pre-holed) around the foundation so that it waters with the sprinkler timer too. In the past, the spray heads sprayed a mist everywhere but never really wet the foundation unless you water frequently. This allows less frequent and I like the fact that one is pre-drilled and the other allows you to put the drip heads at the plant. I would have rated 5 star and 5 bar value, but there is a major disconnect in the section for fittings. There are two kinds of options offered, one by Rainbird and one by DIG. To connect to a 1/2" sprinkler location, you remove the current head and fitting and put a riser to connect to the hose. Rainbird sells a female 1/2" 90 on one side and with a barbed fitting for the hose inside diameter. It does not work on the DIG as the barb is too small for the DIG inside diameter. The Rainbird fitting that doesn't work on DIG ($1.93 each). It took a long time to figure out that the DIG solution is a female 1/2" 90 with basically a male garden hose threaded 3/4" end (Q59) which are $1.75 ea. Then you have to buy a female hose connector with a female slip fitting for the hose (#50001) for the 700OD on the tubing ($2.17 each). Worse is that the Q59 fittings are near impossible to find in The Home Depots. I had to go to 4 stores to find 12 of them for the 12 different locations. That makes the investment for me $50 more for the DIG instead of the Rainbird hose. The DIG tubing (5 rolls) offset this at $3 roll cheaper and I prefer the black color which blends with compost. All in all, the product is great with either solution but the fitting cost (Ts, 90s, and end caps) can add up quickly. April 28, 2015
Rated 4.0 out of 5.0 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 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 5.0 out of 5.0 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 5.0 out of 5.0 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 5.0 out of 5.0 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 2.0 out of 5.0 by Noisy and flimsy This drip-tube drips, but it makes weird whining sounds when it does. It also collapses rather easily, making it difficult to punch holes in it for additional drip spouts. (The controlled 1 gph drip ports that are built in are spaced every 18 inches, so additional drips are sometimes needed for specific plant locations.) Overall, I'm not so impressed with this stuff.

Rated 4.0 out of 5.0 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
Rated 1.0 out of 5.0 by Many leaks after 6 months Worked fine for a while then it began leaking/bursting at many locations after 6 months. Not worth it. May 22, 2013
