Rated 1.0 out of 5.0 by Bruce nice design that leaks and cracks
Just what I needed for a project, but the emitter ports leak on 50% of the units, also it is real easy to crack the base when screwing onto the riser only hand tight. If you decide to use the product buy several spares.

Rated 5.0 out of 5.0 by mkd545 Well Made, Easy to Use!
Unlike the 8 port manifold which has individual port adjustment the adjustment on this one effects all 4 ports. It adjusts easily, is well made and durable.

Rated 5.0 out of 5.0 by Jim Easy to use and install
Fewer moving parts than other similar products thus less chance of something failing.

Difficult to attach the drip lines however, it helped to soften the last 1/4 inch of the line in a cup of hot water before sliding them over the nipple. Some leakage around the connection of the nipple and the head, but not enough to be of much concern.

Rated 4.0 out of 5.0 by Dan Does the Job - Works well
We've been trying to reduce the amount of water used to water our planter areas and to target the specific plants we want watered. We've found that it often takes several 1/4 inch sprayers to do the job. The ORB 4-port and 8-port manifolds are just what the doctor ordered. They're a bit spendy though.

Rated 5.0 out of 5.0 by retired2012 Great for spot watering
Needed to water 4 spots in a small area, this unit worked great and you can adjust the flow too.
can use one or all four.

Rated 1.0 out of 5.0 by Weezeloner I'm not special after all...
Well, like everyone else on here, my 4-port manifolds are leaking. These things really are terrible. They are flimsy, so attaching your drip tubing ban be quite tedious. I'm actually shocked that they still sell these.
However, I feel that if you adjust the pressure to the minimum (turn the dial at the top clockwise) and you utilize all four ports, then the leaking is minimized. Obviously, not a real long-term solution.
To be honest, I have found the eight-port manifold to be much more reliable. Even, the two-port one is better but only marginally so. I have had a 25% (1 of 4) leak rate with those. But that is much better than my 80% (8 of 10) leak rate with these!!
Stay away, if you need multiple ports go with the 8-port or the 2-port.
